I switched to OVO in January, Between January to June I had apparently used £2500+ worth of electricity. An engineer came to check my smart meter in June because the smart meter was not sending any reading. The smart meter was fixed and started sending meter readings. I was told the readings will get backdated and the adjustment will be made to my billings. That has still not happened. I made an official complaint to complaints@ovoenergy.com on the 1st of August with evidence of what I have actually been spending since the beginning of the year. I called the customer service to start a case to resolve this. I have still not gotten any kind of response.
What else can I do to get a response because this is annoying
