I have had a long running battle with SSE over my electricity charges which differ from the charges shown on my smart meter. a difference of £300 -£400 per quarter. Also my water heater does not switch off at end of night rate by two hours in favour of SSE. I have written to Customer Services and e-mailed them-no response. Have constantly phoned and the call handlers must be trained to tell customers what they wanted to here then did nothing. Took two payments from me on the same day in one month. SSE claimed that my bills are correct !!! To top it all SSE transferred my account to OVO along with my problems, otherwise passing the buck. OVO quite rightly refused to entertain my problems they state that it is down to SSE to sort out. SSE Customer Services are a total shambles. Come on SSE take some responsibility. OVO online accounts are in line with my smart meter readings and costings. Am awaiting my first actual quarterly account from OVO.
