One of the worst energy companies I have ever been with. They over charged my account by £2000 and claimed it was because I had never entered my meter readings monthly even though I did. When I tried to call customer service to get it sorted they hung up on me, and I tried emailing serval times and got ignored until I threatened legal action, which is when they conveniently got back to me. When my solicitor contacted them they also began not responding to him, until I got a email declaring there had been a “mistake” and the amount owed was £0. I truly don’t understand how this company can claim they are the best when they’ve done nothing but scam and ignore people. And even now that I have proof I owe nothing, I’ve been getting scam calls nearly everyday on the behalf of Octopus Energy claiming I have an unpaid bill. They are unreliable and thieves, every person that I have ever spoken too about octopus have the same stories and EVERYONE is always somehow in credit on their account, even if you manage to use no power at all. Would give them 0 stars if I could. Save yourself and don’t go with them.
