Continued Billing after Contract Expired

My contract with Planet Fitness expired in Apr/ May 2015.. Details and the mails I have sent to Planet Fitness are below can be made available. Query Ref No: ***. On the dates below, I also stated to Planet Fitness Agents who continued to call me that my contract with them had ended and that they should make sure that billing stops and that a zero balance is effected to my account. Planet Fitness however never stopped and continued to bill me exponentially at that.
