Stubborn Virgin Active

I contacted your offices some weeks ago to cancel my membership as I am experiencing a high risk pregnancy where I am not able to make use of the gym. I spoke with retentions consultant Dayna Veldsman on various occassions explaining that I had previously been on Multiply and left them. My partners membership was cancelled when we left yet mine still continued for some reason. She advises that I have to pay a cancellation fee of R9000 odd. What nonsense is this? I did not sign any 2 year contract as she is saying. I explained all of this to her and yet this morning my account is still debited. This money needs to be transferred back to me and no further debits may be made. Failing which, I will take this matter further.
