I have spent so so so so soooo many hours on the phone to Powergen it's unbelievabe!
I was living in some rented accomodation last year and a few jobless arses were moved in by the landlord to fill some rooms. Anyway at the end of the day they wouldn't pay any bills so I settled my share directly with Powergen and moved out of the house, also informing Powergen of this and they took my name off the bill.
6 months later I start getting phone calls from them asking for this money I owe them. It turns out the landlord rang them up and put my name back on the bill telling them I hadn't moved out
At the end of it all I spoke to a Powergen supervisor and they were no real use at all. I confirmed they had no real contact details for me except for my old address and asked them how exactly they were going to get their money from me! I said feel free send round some debt collectors and cut us off for all I care as I haven't lived there for 6 months
