Planet fitness double debit ****

Planet fitness gym is a ****, I signed with them late-last year for an amount of R249 and since December they have been debating me twice and when I call their head office they don’t answer and the sad part is when they want business from us they are so nice, yesterday I went to mall @55 in centurion where I signed my in contract , to cancel my membership because this gym is ******** us the attitude I received they didn’t want to help me. People please be aware of this gym they are a **** they make us sign for a certain product then from the they will double debit you every month and when you contact them they won’t reply, I have been contacting them and till date I have not received a reply from them
