My grandad has just had a key meter fitted 3 weeks ago. he was on cards b4 that. afte 2 days using the keys the meter was using electricity very fast as much as £5 a day where he was using £10 a week .. he rang powergen up and they read it and said he owed £300. then my sister rang him up on his behalf and they said it was £90. He obviouisly cant owe any due to using cards!? And he cant afford to keep putting in £5 a day... they said they are taking it off him by meter.
Where does he go to get this sorted out? Is there any number he can ring to get any advice on who can help him?
