Membership Cancelled

I am disgusted at the level of incompetency from this pathetic company. I did an online membership cancellation request on the 28/12/2014. I only received confirmation of the cancellation 15 days later, after my account was debited without my authorization. I then reversed the debit as i don't owe this company nothing, it's not my problem my query was attended to 15 days later. Last month planet fitness kept on debited my account without my authorization again and i had to bare the costs of debit order reversals. I cancelled my membership with you and yet day before yesterday 2 debit orders that were not authorized by myself went off an amount of R655 and another of R1350. I am really livid and really going to take action against you guys. I blocked your debit orders that i never authorized and if one more debit runs from my account, the will be hell to pay. I suggest someone calls before end of business today or i will get my lawyer involved in this.
