Where to start? 1. Engineering is disgusting..they outsource the work to firms with no people- 6 months for an engineer to fix broken meter equipment. 2. It broke again? (within 4 weeks)- Sorry hit the back of the queue."will be months" 3. leaving this company?- good luck getting any balance back. left in January-- still waiting!! 4. Customer service..hahaha. have made 30-40 calls -- read above for results. I have had complaints upheld by the Ombudsman, have been bounced around 10's of Ovo employees and provided with endless problems. as another example...OVO have continued to take DD money when I have left and hold hundreds of pounds on account. ---In summary--- If you: - enjoy above average prices without access to engineering support, - are looking for chronically poor customer service - want to fight for your money in excess balance (£600) months after leaving. & you dislike yourself....Then OVO Energy are the company for you!!
