Bad Service

I cancelled my membership with this company last year September and Payment was supposed to end in January. The customer relations are awful and unwilling to help. I have been requesting them to call with no response. No one tried to call to assist me with the new statement they sent because they overcharged me. Now I am getting a call from some debt collector confirming an amount that is not on that statement sent by customer service at planet fitness. I have been requesting for assistance with no response.
