Npower had over £675 in credit which I asked to be refunded. After being told 3 times it would be refunded they didnt because the gas meter had been fauklty and not giving a reading. Npower knew that it was faulty and did nothing about it until they were asked to fit smart meters. They then refused to rrefund the credit because they were going to average usage and charge first. They knew the meter was faulty for a few months so in my opinion its their problem and should have moved to correct it as a matter of urgency not held onto my money so they could take a cut to cover unmetered usage. Distugting.
