What an incompetent company. They have sent me a text stating I owe £1300. I never have had an account with them, I have called them up on behalf of my son though. I explained that he left the rented property and closed the account, OVO confirmed this by reimbersing him . It is the Landlady that owes them money, they agreed this in January but now have sent a message stating he owes £2000 last month and now this has changed to £1300 when he left the property last August! It is against an account number that is not even his. They do not know what they are doing, I will never deal with this company. Ever. Their customer support is based abroad and dont care what bedlum they cause. I will be contacting Ofgem and seeing if legal action against them can be taken.
