Where do I begin? I have been with octopus energy for around 2 years. I was consistently in credit well over £500 so I decided, due to feeling the pinch to ask them for some of it back. After a seemingly long delay, and me requesting 3 times, they emailed me that there had been some issue their end and I hadn’t been billed correctly (even though they installed smart meters nearly a year ago) and I now owe them £1351??? So my question is this? If I hadn’t asked for some of my money back then this “error” in billing would had continued “ad infinitum” and god knows what they would claim I owed them. The other question for me is that if you go along to have a smart meter installed then how the hell can they not get it right? I have been put into massive debt through no fault of my own and have no clue how I’m going to pay it and keep the services on in my house. Absolute shambles. They offered me a measly £30 for any inconvenience caused which is hardly going to go anywhere near putting this matter right.
