Planet Fitness poor service and debiting of accounts with no contract.

Planet Fitness has been debiting my account for many months with no proof of contract ! I have tried stopping their debit orders and made email and telephone calls to correct the situation. its been 4 months i am still waiting for them to get back to me to prove that I have a contract. I know that I cancelled the contract years ago, and they promised that they would get me proof of a current contract/ membership within 48 hours then it became 72 hours then it became an unknown length of time because they need to go back in their records and send the information to the branch manager! the facts are they have now forced a debit order, they tell me my account/membership shows cancelled on their new online system - however i have many many months of debit orders that I want to be reimbursed, plus the current forced debit order amounts. IF they say that i have an account and they could see my email address- why have I not had any emails from them regarding my supposed account - not even updates from them on debit order or contract increases. This company simply does not get back to me, they refuse to put me through to a person who can resolve this. and just keep repeating that they are waiting for the documentation to prove i had an account/ membership. Don't ever take out a contract with them! as they simply wont help when there is a matter to resolve.
