This is the worst company and they have the worst customer service very rude. I was with SSE I have direct debit my bill have never gone past £300 a month. And in January OVO took over SSE, I was away could not send meter readings for January and February and this company estimated my bill and charge me more than 700 pounds by march even thought I have direct debit my account was over 900 pounds in arrears. I have been calling them for the past month to query my bill but all I am getting is the rudest customer service I have ever experienced I am not exaggerating I had to be the one to de escalate the arguments. And what makes it worst in march I sent them a meter reading and my bill for that month went back to around 300 pounds that should tell every sensible person that they over charged me in January and February but no they won't hear that as I am here frustrated with them my account is still over 700 pounds in arrears despite my monthly direct debit and they keep saying to me my smart meter sent them meter reading and I keep saying to them I don't have a smart meter but every time I call is the same issue and now I have given up. Its sad that the government does not protect the ordinary people from companies like this, they scam us any how and get away with it because they know they can get away with it. Am here to say to people to stay far far away from OVO. They are bad news
