This has been on-going since September 2024 when we switched my father's service. The previous supplier So Energy installed a smart meter in the house. Hiowever, this has never worked correctly due to a very porr mobile signal in the area. Octopus took over as we expected better customer service. Despite sending images of readings and raising concerns that the economy 7 hadn't changed between each reading, the company either don't respond to emails, one deals with different people -I think I am dealing with the 6th individual, send an engineer out - who agrees that it isn't working and says they will get it changed (that was back in December) and still the bills rack up. This is for a single man, an elderly widower, who has been badly let down by Octopus. If you look on the Octopus energy complaints Facebook page, it is a sharp constrat to the oustanding customer rservice they say they have. When things are going fine, they are great, when things don't work, they are very poor indeed.
