I have yet to receive anything from them after sending them that recorded delivery, thanks for the advice and hopefully that's put an end to their false claim.

Hi, I was a member with DW sports on a month to month contract, started in the summer of last year. I cancelled my membership with them I believe just after new years 2012 by phone, then a month later cancelled the direct debit. Last week I received a letter stating I owe 53 pounds including a 15 pound penalty fee. Today I have received a letter from them about passing it onto their solicitors. How do I take action to resolve this?
