CONTRACT SIGNED NOT DONE CORRECTLY, BILLED ME

I SIGNED 5 CONTRACTS (MYSELF, 3 SONS AND my DAUGHTER) before 15 January 2015. reason my 3 sons would gym free for the whole year (Special Virgin active had). My 1 sons contract expired which was signed on 9 January 2015. Reason for that being Tumi Ndweni did not complete the contract correctly and was not authorised by management and she never informed me. I paid my deposit and my first instalment went of correctly on the 31st of January 2015 for the amount of R669.00. We went to the gym everyday and the card gave problems after a while and I asked the ladies at reception what's wrong and they told me that I have to make payment of R70 for an outstanding amount on his previous contract. I paid that. and the card still gave problems. Mohammed Banoo in sales said he will sort the card out for us. I told him that Brandon's contract is for free as we signed before the 15th of January 2015. He said that it is no problem and came back stating that it is sorted out but he had to do that contract over again and everything is sorted out. did not tell me that a new contract have been done and I will be billed. Still waiting on contract to be fixed and be refunded.
