Would give zero stars if i could

Would give zero stars if i could! Absolutely appalling service. I moved over to sainsburys energy and they confirmed my tariff. When I went to check on my account a couple weeks after joining my tariff had been changed to a more expensive one and no one had contacted me. That was nearly 3 months ago and I am still battling to get my tariff updated and my meter fixed after it magically stopped working after my switch to sainsburys. I've raised a complaint and been told I need to wait at least 30 days for an engineer appointment. The appointment couldn't go ahead and I reached back out to the person dealing with my complaint. He again asked me for a date I was available in 30 or more days time. How is that acceptable service. Ive still not been provided a replacement appointment and I am still on a more expensive tariff. Just disgusting service, the complaints handler uses stock responses by the looks of things as they don't always make sense to what I've asked and I've had to chase every single response so far.

I am incredibly sorry to hear about the experience you've had since switching to Sainsbury's Energy. It's completely unacceptable that your tariff was changed without your knowledge, and that it took so long to rectify this and fix your meter. I truly understand your frustration with the delayed engineer appointments and the generic responses from your complaint handler. This is certainly not the service we aim to provide.

I want to personally look into your account and every issue you've raised, so I have sent a request via Trustpilot for your account details. Once I have this information, I will investigate immediately to get this rectified for you.

I hope to hear back from you soon,

Thanks

nectar points…

I’ve been trying to get nectar points added to my account for about 4 months. Missed the double Avios reward etc. conflicting information has been given about how we need to go about it. I think Sainsbury’s should have picked another provider to white label because eon next are just not able to handle the relationship.

Good afternoon Amanda,

I am very sorry to hear of the protracted difficulties you've experienced in getting your Nectar points added and that you've missed out on associated rewards such as double Avios. I understand how frustrating it must be to receive conflicting information and why you feel E.ON Next is not managing this relationship effectively.

I would like to investigate this matter thoroughly for you. However, I have been unable to locate your account with the information currently available. I have sent a request via Trustpilot for your account details. If you could please provide this information, I would be pleased to look into this immediately and assist with resolving your Nectar points issue.

I look forward to hearing back from you,

Warm regards

what ugly customer service experience…

what ugly customer service experience ive had from
them they keep passing me between nectar rewards and sainsbury energy over a dozen times constant emails from pillar to post .
just because i want to link my 5 energy accounts to my one nectar card the assistants have No clue whether it can be done nor BY whom !!! as ive had it done in the past im telling them and when she claimed she done it does not even register on my accounts profile ..
what about people with two homes or more and one card ?? just have it registered to one card i pay the bills it my entitlement to have points from all five of the energy accounts regardless if im the same person its should still be X5
if someone could rectify this would be great

Good afternoon Mr. S,

Firstly, I'd like to extend my sincerest apologies for the delay in our response to your review. Unfortunately, we've had some system difficulties, and I'm very sorry it has taken some time to get back to you.

I apologize for the difficulties you've experienced in linking your Nectar points and the fragmented customer service you've encountered. It's clear that the conflicting information and repeated transfers have caused considerable frustration, and this is certainly not the standard of service we aim to provide.

I understand your concern regarding how multiple energy accounts or properties are linked to a single Nectar card, particularly given your past experience.

I'd like to thoroughly investigate this for you. As I've been unable to locate your account with the information available, I've sent a request via Trustpilot for your account details. If you could please provide this, I'll promptly assist with resolving your Nectar points issue.

I look forward to hearing back from you,

Warm regards

terrible sadly… …

at least 3 times a year i get my bill doubled for absolutely no reason or there’s an error or my smart meter is apparently not reading even though it’s new. sainsburys are unfortunately the worst energy supplier i’ve ever used and im so relieved i have swapped to Octopus. with sainsbury’s i was often very stressed to get an email 5 days before my payment due and it would be doubled unnecessarily. , Octopus have been hassle free, transparent, and fair. thank goodness,

Good afternoon Emma,

Firstly, please accept my sincere apologies for the delay in our response. We've had some system issues today that we weren't aware of and so I've only just seen your review to be able to respond.

I am truly sorry to hear about the consistently stressful experience you've had with your billing and smart meter issues, and that you felt your bills were unnecessarily doubled. It's clear that receiving those emails just days before payment was causing you significant stress, and I sincerely apologise that our service did not meet your expectations for reliability or transparency.

I understand your relief at finding a provider who offers you a hassle-free experience. While we're sad to see you go, your feedback is incredibly valuable, and I appreciate you sharing it. We are always striving to improve our services, and your insights will certainly help us in that effort.

I have requested your account information so I can look into this for you to ensure we were diligent in your payments and to explain the price increases that occurred.

I hope to hear back from you.

Warm regards

I have been with Sainsbury's energy on and off for about 12 years.

I like the telephone customer service but dislike the robot help when calling.

I needed to call and talk to someone from customer service team because I couldn't find my latest bill on my online account.
