Just Direct Debit me for an interest free loan!

I finished paying for my iPhone and changed to a SIM only tariff, which was an ok price. They then direct debited another full month's invoice, putting my account in credit, but would not refund the overcharge, despite me calling the foreign call centre, who must be employed to just sit there and take shit all day long from aggravated customers in the UK. A manager was supposed to call me, but never did? Instead, they just take an interest free loan from me to fund their business!

Paying for a service we can't access

We had a contract with daisy and had to close our business because it simply wasn’t viable, and we’ve vacated the property. Despite this, Daisy Group is still charging us for a landline and broadband service we no longer even have access to, purely because we’re tied into a contract.
I understand contracts exist for a reason, but there should also be some level of fairness and common sense when a small business closes down. Instead, the response has been completely inflexible, with no real effort to help or find a reasonable solution.
Very disappointing experience, especially at a time when many small businesses are already struggling.

Bad experience

Bad experience, not valued after years and years as a business customer, could not resolve my issues, the simcard was not working, however they still expected me to pay for it. was forced to close it down and pay the full contract for a service that was not working. No apology, no contact, no help, no service - but they were happy to take that final payment

Zero stars would be too high. Absolutely rubbish service. Needs a sim swap as my business phone stopped accepting calls from non o2 networks. New sim arrived did a sim swap. New sim not activated and now business phone is not receiving or making calls. Will be moving supplier immediately

Cancer

These clowns rejected our company for a business SIM at a paltry £17 a month despite us never missing one direct debit in 8 years and change trading. I had already cancelled the shop WiFi too. Now we have no way of taking card payment over the busy Easter break. I genuinely thought it was an April fools joke originally, but no, they really are that incompetent.

TERRIBLE CUSTOMER SERVICE

TERRIBLE CUSTOMER SERVICE
Apparently o2 have a call centre full of employees who struggle to grasp basic English. They all read from a "script" and ignore your actual request. When you eventually get to the deapartment you need to be, they either cut you off mid conversation or blatantly ignore why you are actually calling.

As a business we will be reviewing our options at the end of the contract - o2's price is great, but the customer service is possibly the worst out there.

*Queue the generic repsonse on trustpilot from o2 customer service acting like a concerned priovider who wants to "help"

No portal - you even can FAX in your details!! and offshore staff who are rude or can’t speak English properly or both, HIDEOUS wait times and multiple department transfers !! Omg - I’m leaving and going to Sky. O2 - your offshore debacle is costing you customers and your process needs to be updated .

Absolute joke of a company.

Absolute joke of a company.
I have been out of contract with them for some months, email me to tell me they are putting up the price on my account!!!
Was originally told my bill would be £16 per month, with this so called increase it was set to cost me £38 per month.
So decided to contact 02 to obtain. My PAC code, after 5 transfers to people and then being hung up on, got told couldn’t do it for me ????
Direct debit cancelled, now using a different supplier for £10 per month .
Staff are rude, unhelpful and arrogant.
Avoid at all costs.

I'd avoid O2 business if you favour efficiency.

Historically, I've been with O2 for 10+ years. It was natural to stick with O2 when I became self employed some moons ago.
Gradually, the customer service got worse. It used to be great, you'd get through to a CSA as a business user quicker and more efficiently than a consumer customer and issues would be resolved the same day I call.
After 10+ years, I've phased out using O2 business and either moved on or moved over to using O2 consumer contracts because its so much more pleasant dealing with O2 consumer CSA's, and it's such a breath of fresh air being able to go to an O2 store and speak to someone who is willing to help.
The last 2 contracts I had with O2 business has been an absolute sh*theap time. The first one; some absolute belter made a mistake with the contract renewal to the point we had no service on the phone for months. When we came to try and resolve it, the phone line was disconnected. Well over 6 months of back and forths with not even a 'sorry' when I decided to give up and let them close the contract down.
Second one? O2 invoiced me some extortionate amount (Over £1k iirc) for INCOMING phone calls that we never even answered (records show) and their justification was because we NEVER OPTED OUT of INTERNATIONAL calls. Now, over a year later because of the amount of credit we accrued because of that mess I'm trying to close the account. I went to my local O2 store, opened a new O2 Consumer contract with the hopes of keeping the original number and with the lovely staff on the phone to O2 business on my behalf to be told they cannot generate a PUK code on a saturday and to 'try again monday'. Lo and behold, its monday. I call at 8am, on the phone to a CSA to be told that I MUST HAVE the phone on me in order to pass security and generate a PUK. I own the contract, I passed security to talk to you. Why on earth do I need the physical phone NOW when all I'm trying to do is RETAIN the number for business purposes.

Having left 02 after being with them…

Having left 02 after being with them nearly 20 years, I get a bill with a credit. The credit isn’t repaid on the normal date, I call up having googled the number as on the finial bill they leave off the number!
Anyway on the phone I am informed I have to call up to get my refund, then a manager will call me back - not even sure this will happen.
Appalling service which reinforces why I left, do not recommend.

Awful customer service. The business website makes it hard to find a phone number to ring.
I have been a customer for TWENTY TWO years and I wish I could get out of the terrible loop of horrible poor customer service from 02.

Taken 2 hours so far to try and cancel my account. After 11 years I would expect better. Strangely failed security despite having hard copy of bill in front of me.

Painful and slow bereavement process

My father died and I tried to follow the instructions on O2's "bereavement" webpage to transfer his number to a PayAsYouGo number in my own name. This is important for some administrative issues (e.g. security codes which get texted to his old number).
This process has taken, so far (still not reached a successful resolution), 4 phone calls with O2 totalling probably 2+hours with a succession of staff many of who don't seem to know their own process. I was promised a callback today and it didn't come. I'm sick of their stupid hold music and talking to offshore staff in the Philippines with broken English (you don't "have a load" - you "buy some credit").
This kind of painful process is the last thing someone needs when dealing with a bereavement.

UPDATE following O2 response below: I provided the information. I’ve emailed their team 3 times. I’ve called their offshore call centre 7 times. They have not sorted this. I will never use 02 again.

Worst 50 minutes of my life, just to say yes!

I just spent the last 50 minutes on the phone with O2 business. Just a renew my contract keeping everything the same and just saying yes proceed.

First, I couldn’t understand the lady on the phone, with an extremely heavy accent.

Secondly, after waiting 20 minutes for her to generate the documents, she then said I had to check the email and I told her I was not able to check my emails at that time. To be told well then she will wait for me to do so because they need to be checked without any prior warning the very beginning of the call that this invisible button is necessary.

To then tell her I’ve been on the call already for the last 40 mins, I didn’t need to hear any o2 guff, or want to hear anything about the priorities or marketing no nonsense does she have to tell me.

So whenever she started reading off the sheet, I kept telling her to stop and just to get to the end I don’t need to hear it.

It was painful!!!!!

Honestly, O2 get your act together.

We don’t want to hear all the nonsense, we just want the price and say to proceed.

Disconnection fees for paying ontime by card!

Paid a balance by bank card, few days later they take 2.5k out of my bank for a disconnevtion fee. Since then we had the disconnection fee removed and cancelled our direct debit to pay manually by card each month as we could not trust them. Turns out the only way to pay is by actually speaking to them which involves a very difficult verification process that as the account holder id not expect to fail but often did.. i do not know how much theblast invoice and what date it is no.. not a computer 24/7. Stupidity, inconvenience and then i find they keep reporting this to my companies credit profile. Late payments recorded because they make it inconvenient enough to warrant only getting called when i notice a disruption to service.

Save yourself the hassle of being operationally crippled for 3 months whilst they hold onto your funds and keep your account 2k+ in credit and then shoe horned with bad credit report notes because they dont know how to add a "pay invoice" link to their website like they are stuck in the 1980's.

Issue addressed and resolved to a positive outcome by O2 businessf)

Update: O2 has addressed the issue we have faced and have refunded us. Overall, I am pleased with the outcome, its a shame it took a trustpilot review to get it.

Update: I have submitted the information they have requested today, lets see what's happens

I am appalled by the predatory billing practices of this company. I cancelled two mobile contracts, well within the statutory 14-day cooling-off period. Despite having never used the numbers, the company is attempting to charge me for a full month of service.

Under the Consumer Contracts Regulations 2013, I have a legal right to cancel distance contracts without penalty. Forcing a month's payment for an unused, cancelled service is not only a breach of consumer trust but a clear attempt to bypass UK law.

I have already revoked my Direct Debit and will be escalating this to the Ombudsman if they do not immediately confirm a £0.00 balance. Avoid this company if you value your consumer rights—they make it easy to sign up but will try to squeeze money out of you even when you legally owe them nothing.
