False Sales

Good day. After mailing headquarters repeatedly and also speaking to Sancardia staff I still have no solution. I signed up for sancardia branch before it was finished building. When I signed the contract. .the sales person REPEATEDLY told me and my 2 colleagues, that this contract can be cancelled at ANY TIME after 6 months. That is the whole reason why I signed. Knowing well that I will NOT be able to go to gym after june. I'm in the SANDF and I am deploying to DRC where I will be working for the next year. When I spoke to sancardia staff about this sales person I was told that she was let go and they can't help me. I want this contract cancelled because I signed under false pretences. Extremely disappointed with the help I have recieved regarding my situation
