********transaction from my account

In Octocber 2013, I joined Body Lab Gym and Aerobics. i signed a three year contract with at R300 per month and R149 in November and April for the duration of the contract. In April 2014, Body Lab deducted twice the amount that was agreed upon in the contract. When I went to enquire from the bank, the bank informed me that both the amounts of R300-00 was deducted by Body Lab. I requested the bank to reverse the amounts. After a week, Body Lab sent me an sms instructing me to pay R700-00 rands into their account. I paid in R800-00. I was surprised when I was called by their lawyers, Bennet and Associates informing me that the account was handed over to them. I explained to them of what had happened and a lady by the name of Rinda asked me to send proof of the double amount that was deducted. After receiving the proof Rinda had insisted that I pay the money irrespective of the ***** that was comitted by Body Lab. I refused to pay the money and asked them to take the matter to court. Last month I received a letter dated 10/09/2014 from ITC Business Administrators instructing me to pay the money to Bennet and Associates. When I called them I was told they sent my file to a garnish co.
