Incmpetent staff not cancelling the contract

I joined planet fitness about two and half years ago, mid year last year my contract ended then I received an sms notifying me that I need to renew or I will be on month on month. I went to the branch in Pinetown in September after I was involved in a car accident that I would like to cancel my membership as I want to go back to my old gym. I was told the guy who joined me had left then spoke to the ladies as reception and I was told they will make a note and I will receive ref via SMS. In Dec I received a call that I had not paid I questioned was told had not cancelled my membership, then requested to cancel I received ref PP ********** 9 again in January 25th I received another sms that I am owing I called the number I was given by the lady who called me in Jan ********** 463 spoke to another lady who gave another ref PP ********** and said I will receive sms then today I received a call from attorneys that I have been handed over. Hell NO! for what? I did my part and I did what I had to do now you telling me that I am owing you? I am not owing planet fitness anything my contract ended and on the 05th of September I went to cancel now you telling me I am owing you when your *********** staff did not do what they supposed to do then become my fault?
