"Better you do complaint as you can translate the story from Nanda more accurately than me. The comment appended to the Times article is familiar - I know the salesman had Nanda show him the bills.

Worth also saying that I tried to cancel by telephone on the first working day - 6 May. Their customer assistant Lily would not allow me to cancel because they did not have the information on their system and that the earliest it would be worth my calling back was the Thursday or Friday of that week. When I then said I wanted to make a complaint she said I couldn't do that until the same time. When she gathered the contract was not in my name she said I couldn't cancel it but my sister in law, despite speaking no English (the point I was making), would have to cancel it. She assured me that they had access to languageline. When I expressed my displeasure at the situation saying I thought it was a pretty poor show that this salesman should "force" someone who doesn't speak English and had made that clear to him, to sign a contract, she became very aggressive with me. Eventually I as good as hung up on her!
Subsequently I was advised by several people to write rather than phone and send recorded.
As the cancellation letter only arrived at npower yesterday, I will wait a bit before making a complaint to see if they reply.
