Blau Mobilfunk Reviews 

Really annoying cancellation process, inefficient chat, all so outstandingly bad that I made a trustpilot account to tell the world. Oh, and you are really expensive compared to other providers. Edit: Honestly, still years later the worst experience and the most money wasted every gfy

Terrible customer service.
Customer service should be for free. However, this company makes a mistake and charges their clients when they try to report it.
It is impossible to get in touch with them. No email adress or online chat service on their website. The only way to contact them is by calling a phone number (for which you have to pay), talking to a machine and waiting an undetermined amount of time for a person to answer.

The BEST UNFRIENDLY customer service!
If you don't speak german they are gonna make you feel like S h - i - t

Rude, dismissive and after waiting to get through to them, they just cut me off.

Customer service is horrible, rude,i have been write Widerruf, and after 2 months they charged other person account taking money from my not existing vertrag...not answering at even not on emails not on calls.

I am overall happy with Blau. I have never had problems when it comes to the product itself. Though if you have problems and need to get in touch with customer service it is almost impossible to talk to a human being. This to me is really a minus, since you spend much more time on resolving something when not.

Live Chat on the Website needs a login - I can't login because they closed down my prepaid number because I didn't put Money on there for a year.
They literally force me to call the f**king hotline which costs 20cents/Minutes.
There is no email address you can write to.

Blau is beyond bad! I finished my contract in February because of leaving Germany, left and closed all accounts. I told them that, I sent all 50 papers they wanted as a proof but they still won't stop trying to steal more regularly! They bombard me with junk and huuuge bills with made up numbers every day, they do not answer my emails at all, they just come after more and more money! They bring me moral demage and however I write in German to ask for explaination they steal and ignor my requests and charge more. They are officially the most insane and horrible company I ever dealt with! STAY AWAY FROM BLAU AND MOST GERMAN COMPANIES! They are given a green light in their country to do anything with people, just like 80 years ago others there did.

Too bad we cannot put 0 star. Beware from them they are THIEVES. They will do everything on purpose to prevent you from stopping your contract even if you are in your right. They take money on your account and use your personal data without authorisation. They will always find a legal way to take advantage of you. Avoid at all costs if you want to keep your money.

The worst customer service ever. After two years of subscription, while I thought I could cancel whenever I wanted I discovered that they had added another year of subscription and doubled the amount they could withdraw from my account. Nobody within their entire customer service accepts to speak english. This company is a customer disaster. Stay away!

I have been using Blau.de for last 2,5 years. The internet is poor and it is a disaster if you need to call them to the call center. Be ready that they will not solve your problems. They have no offices in Berlin so you cannot basically do anything apart from calling them one more time. I tried to cancel the contract but then they renew it about 8 months in advance... If you call them to require to stop the renewal of your contract, be ready that you will get 30 mins pushy speech to make you stay with this company.

This company is a scam. I bought an allnet pass for 19.99. Thisbworked fine for the first month. Then I loaded 30 euros at theend of the month to renew my subscription. Fine so far. Then I missed a few days then added 15 euros. I though I'd have enough left over from before but they'd been charging me an arm and a leg for roaming during the day or two I didnt have a plan. I uploaded 15 more euros and selected a surf L plan. My receipt says I paid for it but they're still charging me for roaming. Now I dont have enough credit to even call customer service. They'll just eat up your cash without you realizing it. AVOID

This company send me an SMS telling me that my request for moving my number has been received and they will work on it. But I never made such request. I have never in my life heard of this company, until I receive this SMS. I call my current phone company and I also called them and they aren’t able to tell me what to do. They totally violate my rights to choose as I never give approval, I never signed anything. I don’t even have a contract or so. I will for sure go to a lawyer because I think that this kind of data should be protected (my name, my phone number) and not misused by any company.

Disappointing lack of customer service

I was a blau customer for quite some time, then I cancelled the contract to move to another provider. As I had a rolling monthly contract, I arranged to have a new contract for the end of the month that I paid for. Unfortunately, as soon as I cancelled with blau, they cut off service. A day or two before the end would have been fine, but it was done one week into the period that I had paid for. No refund for that time was offered, so I'm bitterly disappointed.

Not f worth the headache don't use it go to a proper carrier

This has to be the WORST customer service in the entire world. I tried cancelling my subscription in July so that it would be done by August and you told me to call you (?) to confirm it. So, I did. And then you said; Oh, well you need to write us a letter to terminate your contract (??). So, I did that too. And now you’re saying you will terminate my contract by the end of OCTOBER (???). I AM MOVING ABROAD IN A WEEK.

You’ve already wasted so much of my time by forcing me to spend hours on my termination. PLEASE just terminate my contract by end of August.

I'd happily give this company -5 for the misinformation and crappy product they provide. I thought I had a great deal when I signed up to their Allnet XL 5 GB for 16 euros a month. The first bill was 34. They said I must have made international calls, so the following month I was very careful to ensure I did not. Next bill 33, almost identical charges. No international calls were made. Third bill, 34. After requesting the cancellation of the contract they informed me that the high charges were due to a large amount of MMS messages. I use whatsapp constantly and made a grand total of 5 local calls for that month. I would strongly recommend that when looking for a German sim card that you avoid this company.

I was not able to cancel the contract. They told they will and never did so. It's really challenging to reach out to them.
I didn't even use my aim card, since I lost it. I wanted to restore it but it's impossible. However, they always send me the bills on time. What am I paying for? I don't even have the SIM card and not able to restore it. They are just stealing my my money. I'm paying for an air.

Never had a cuatomer service that abruptly hangs up. It's been a terrible new mobile phone experience. They are unfriendly unhelpful and down right rude at times. I'm switching as soon as possible with the help of a lawyer if need be.
They don't even deserve the 1 star

Worst company ever !!
It's expensive, very bad Kundenservice, impossible to reach them, they charge a lot of money when you leave the contract.
Don't go with Blau !!!
