cancelling membership

On the 26th of April I cancelled my membership. The agent that helped me stated that he will debit the remaining balance on the 15th of May, he never put in the debit order to debit the amount. I saw that and phoned Customer care and payed the money into their account immediately just to get a phone call from an Attorney stating that my file has been handed over I need to pay them the legal fees after I already payed my outstanding amount
