I signed up for a contract, I was told £86 per month. Before our first bill came, before we sent any meter readings, before we'd even lived there a month, we got an email saying our bill was being raised to £246 a month. This was based on nothing. I took a day off work to fit a smart meter. Smart meter doesn't work and ovo continue to charge a crazy rate for 2 people living in a small, 1 bed flat and barely do anything in the flat as we both work 2 jobs. I try submitting a meter reading, and they say they can't accept it because its lower than the original read, even though I never sent an original read. One customer service member shouted at me and told me to "f*ck off" because I wasn't reading my account number to them slow enough. Another transferred me, where I was on hold for an hour, before being hung up on. DO NOT USE OVO UNDER ANY CIRCUMSTANCES, THEY ARE NOT A GREEN ENERGY PROVIDER THEY TAKE ENERGY FROM THE SAME NATIONAL GRID AS EVERYONE ELSE BUT ALSO SCAM YOU.
