If I could give 0 I would. Dad is 80+ & in credit by over £1200. Despite this going up year on year, they keep taking his money. I contacted them in Oct & arranged to reduce his monthly payment to £5 with a review at 6 month. 26 Nov '24 he got a letter stating the DD was going to be increased to £97 from Dec! I argued this wasn't the agreement & when asking for a refund, they now are making it very difficult for Dad to get his money. I have had a similar issue with my Mum's account with EDF. They have been brilliant, with no issues & I will open an account with them for my Dad in the New Year. Do not use OVO they are a load of sharks & are not an ethically run company.
