After instructing Octopus to supply me with energy in July 2023. Ovo proceeded to try to take over the supply 4 times in 7 months. Each time I cancelled them they made it difficult and blamed an Erroneous Transfer which is not the case. Now they have billed me for over £300 and have made the process to stop this even more difficult. I have supplied documents to help this to find out they can't accept them because they don't have my email address. I then give them my email address 3 times and it is still not sorted. I have two live complaints, neither getting anywhere. Utterly negligent and unhelpful. I couldn't recommend them less.
