I got a "Final Bill" letter back in September saying something along the lines of "This is confirmation of your cancellation, you owe us £121"

W T F?!

Since when did I cancel my account and move house ?

So the missus phones them up and politely informs them we haven't moved or cancelled our account and that they're still taking direct debits from us. She gets passed round several different departs and eventually gets it sorted out (computer error)

I get home this evening to find a letter from a fookin Debit Collectors on my doormat saying they're coming round on the 13th to collect Powergen's money

Stupid useless cnuts
