When I first joined Octopus 3 years ago the service was good and I received monthly bills. Over recent months I have been receiving up to 3 bills a month based on estimated readings. Customer services ere patronising and advised me that I have a responsibility to provide regulars meter readings. I advised the reminders had stopped and was told the tech team would be notified. So far between mid sept and now I have had 4 different bills. 2 based on estimated and 2 based on actual readings. I recently paid a bill following submission of a meter reading. Customer service confirmed I had received an adjusted bill which factored in my updated reading. I duly paid this and less than a week later received another bill for an additional amount ? with no explanation as to where this additional amount has come from. My queries to customer service appear to fall on deaf ears and I have been now advised that I must provide regular meter readings and this will slow down the estimated readings and subsequent bills - please help this make sense. I have stopped my D/D as in no way am i allowing Octopus to take 3 or 4 payments a month out of my account. Sadly I am now reviewing other suppliers.
