Planet Fitness *****ulently debits my account by changing the amount and days of debit after the contract has been canceled and non excitant

10 years gym contract at Planet Fitness Hennopspark Centurion of which a family contract for several years of this. Probably utilized 5 of the 10 years but kept on paying, haven't signed a renewed contract in years and have requested for my gym contract which is actually nil and void to be canceled as they keep on *****ulently debiting my account by changing the amount and the day of debit. Same story with my son after canceling and paying the outstanding amount they still taunt him to pay R 899 cancelation fee and yet his contract lapsed and he didn't want to renew it so it was month to month. They're call center agents and credit control/debt collectors makes all sorts of threats about black listing. Absolutely horrible experience with Planet Fitness and everyone should consider when taking out a contract as they make the cancelation process ridiculously difficult while forcing debits. I hate giving companies a bad rating as I have several of my own but when large companies use bullying tactics to keep customers then the writing is on the wall.
