5 years ago i took out a warranty on a washing machine - we then moved and i continued to pay each month without realising. The company say it is up to me to advise them when we no longer own the machine (we sold it to the people who took over the house). Can i write to ask the company to refund all/some of the money or are they right - i should have advised them. I do not think they contacted us during those 5 years - but of course having moved house we would not necessarily have known if they had been in touch. Is it worth writing to the company or will they always say that i did not inform them of my new address and so can't have any of my money back?
