Nobody wants to help me

I have been calling Zone Fitness for the last 2-3 weeks to enquire about my contract as I know it is coming to its end and I only made use of the gym for the first 3 months. I now want to cancel it but every time I phone nobody can help. I call and I get told that my gym contract is not with St Georges Mall so they cannot help me and when I request them to find out where my contract is so that I can cancel it I get told that they cannot help me and I need to phone around so I tried calling Cape Quarter and they tell me exactly the same thing. I don't see how this is my problem and I don't know why Zone Fitness cannot help me but they are not complaining that they are debiting my account every month and I don't want to stop the debit order as it will reflect badly on my credit record. <br> I am really upset because I don't see why I should be paying longer than I should especially considering that the last time I saw the inside of the gym was probably a year and a half a go. I don't know where the contract is neither do I know where my card is and I actually don't care where it is. You should have my contract details on system and if not, don't request me to call around, not my problem
