Since OVO took over my contract from Southern Electricity it has been a nightmare. Their first action was to over estimate my usage & decide that my electricity bill for January alone was nearly £3,000. Their second action was to increase my monthly DD each & every month to the point that they wanted nearly £900 a month. With SE it was under £200 for both electricity & gas. I have spent an inordinate amount of time for the last nine months attempting to obtain a refund & trying to get my DD reduced to a sensible figure. Each & every time that I believe I have got somewhere by explaining the whole situation, yet again, to try another person who will “personally take ownership of my problem” it falls flat once more. The next person knows nothing of the previous discussion/ agreement. Hours & hours on the telephone. Numerous meter readings sent in. All ignored. FINALLY I obtained a refund & managed to reduce my DD to a sensible figure. Guess what? Before the first new DD had left my account I received yet another email stating that my DD needs to increase by 50%! Jeezus effin whatever. DO NOT START AN ACCOUNT WITH THESE PEOPLE. IF YOU ARE WITH THEM GOOD LUCK & LEAVE ASAP. I WILL BE.
