Planet fitness poor customer care

I once had a membership with them while i was working at Rosebank and before i moved to Eastrand i went to the branch to cancel they told me that itll deduct for few months then itll stop or i had to pay that amount however i didnt have money then allowed it to deduct until it stopped and yes it indeed stopped until last month after so many months they deducted R485.12 and i went to my bank to reverse and now they deducted 2 times on my account and i am so frustrated cos i no longer gym with them and i went to their branch now what am i suppose to do for this to stop? Cant they see that my acc hasnt been active and why now? I dont workout with them anymore please they should check their records cos ill close this account i cant bd reversing debit orders or changing my account for them...you sort this out plz. I dont even remember who i spoke to
