Updating nectar card to account

I needed help to update my account settings. I found the help I needed through the what’s app option and all instructions were very clear and very helpful! So with clear instructions I managed to sort my account out successfully! Thank you Shane for all your help today!

Changing tariff

Amanda was very helpful and gave me my dual fuel usage for the year. Also gave me the breakdown of a fixed tariff Sainsbury's have which is cheaper. Friendly and efficient. Thank you

Tried other ways sort out a small problem,to not a lotnof joy. I noticed you could use WhatsApp,which i did and within a matter of minutes my issue was resolved.

New to this provider but if the customer service continues like this I should be a happy customer.

Great customer service and speed as well

This team are just simply the best. Any questions or queries are answered promptly and effectively.
I was with the so called best service supplier in the UK however, I fail to disagree, Sainsbury's/E on are the best, by far

Woeful customer service

Woeful customer service from an advisor who was completely driven by the system. My account was in debit because of winter usage and I was asked to either pay the balance or increase my dd. It was impossible to get the advisor to accept that as we were now moving into the summer months the account would soon balance out. 12 emails to get nowhere and still waiting for compensation for time and aggravation. Will not renew. Eon is the problem I suspect.

Amazing supplier - 10/10

Shane and Rebecca were a fantastic help when setting up my monthly payment and resolving an issue with a reward payment. 10/10 service.

Best energy provider I’ve been with

Surprisingly helpful and easy to deal with. Not what I was expecting at all. I called to make a change to my DD payment and whilst they did that quickly they also suggested a cheaper tariff that I should be on and then put me on it, all, within 10 minutes or so. Very impressed. In these times of massively high energy priced having a company you can actually talk to and who seem to want to help is a massive plus point.

I would not even give this company a one star. Today I got another quote for 17k for electricity. Saying how it’s discounted. How is it 2k more than the last mess up you did. Please please if you do one thing today.. go with another supplier. Avoid this company. See my other reviews! I think the other good reviews are fake! No way this company has 4 stars.
