Took extra £100 from my account after the final bill was paid when I switched supplier since then i have tried to get my money back and was told twice that the money will be in my account in 7-10 working days. After more than month all of a sudden I receive a email with some dates and charges and reverse charges and this time i am being told that £100 has been adjusted due to a reverse charge on my energy account dated back in 2021. Absolutely ridiculous I have a smart meter and it sends out readings regularly . They only came up with this story once I asked them for my money and if there was any issue with the readings ( Which I do not agree ) is this how octopus deals with it after many years and on extra payment taken from bank account . After speaking to the manager Amber she admits that errors have been made on my energy account but refuses to pay back me the money. Very frustrating I expected better from octopus but i was clearly wrong.
