Ovo have systematically increased our direct debit despite being nearly £500 in credit. For the third time since we said our DD does not need to go up because our main source of heating is logs, they have increased again to nearly £200pm which we cannot afford and do not need to do. They are not taking calls and when I asked their Bot to put me through to a human I was told I was 201 in the queue! I actually have a job to do rather than spending all day on the phone to repeat the request we can already made. DO NOT PUT OUR DD UP!!!! You have more than enough of our money already.
