OVO took over my energy supply from SSE in July 2023, at the start October they replaced my old electricity pay as you go smart metre while the installed a new gas smart meter then all of a sudden I was due them £150 which they remotely put straight onto my meter didn't make any sense until last week when I finally received back dated statements and it turn out I received the warm home discount in December of 2022 and that wasn't on any of my statements even though I was receiving both universal credits and PIP. There customer service departments are rude and just a waste of time. The best thing I did was to leave that company
