Still charging after cancelled contract

I have cancelled my contract with planet fitness about two and a half years ago. I even made three appointments at Planet Fitness Witbank to cancel my contract because each time the front desk told me that the contract was cancelled, I would still get a bill at the end of the month. Each appointment the manager of Planet Fitness Witbank would just not show up to our scheduled appointments.<br> <br> I made the front desk sign a copy that my contract was definitely cancelled and that I was NOT in debt with planet fitness. <br> <br> I got a mail that I now owe money to planet fitness and that I have to pay the amount not to be blacklisted. THIS IS UNACCEPTABLE! I was even in credit at the time, when I cancelled my contract! How ridiculous is this?<br> <br> I was not in debt with planet fitness when I cancelled my contract. I even paid a cancellation fee as well so that I did not have to deal with them any more.<br>
