Scam

I signed up to join your gym on Birch acres, a de*****eck was done and Approved on my account. Last week when I was enquiring about my membership I was told it was not active as yet itll only be active once the first debit order goes off. So I asked them to cancel my membership and now they asking me for R150 admin fee to cancel a membership that is not even ctive. This was not on the contract I signed and I am not willing and do not have the R150. The debit order is going to go off my acc in a couple of days. Please cancel this I cannot afford to have this problem. I do not have a phone so if you try to call me u might not get through but u can email me.
