Robbers how can one owe gym R8000

My sister was offered a two weeks free gym voucher and still didn't attend the gym now she is being garnished and they taking her last money every month. Why cause she was never told money would be taken from her account as she was only told it was a free voucher. My next move is to take you guys to Court you are and poor people you guys must give her money back. How can someone owe gym R8000
