Hi,
Apologise, the date I sent the letter and email with letter attached was 29.08.16, had a reply on the 28.08.16 from the gym saying they couldn't cancel the membership as it was a 12 month membership. They also said in their reply that as I had signed the contract i had agreed to these terms. I knew I hadn't signed any contract and so asked them for a copy of my signed contract. A couple of days later they replied saying "I am unable to locate your signed paper work in the office after change of management, ..."
I will cancel the DD this weekend
