Virgin Active Billing Nightmare

I joined the Virgin Active club in Century in 2013 and I moved to Johannesburg. I cancelled my membership within the specified time and have not heard of them. A few months later I get a call proclaiming I breached contract and owe them +- R3000. I refused to pay as I did cancel in time. In 2015 Discovery gave me as a promotion 1 year free membership with Virgin Active and I wanted to sort out the mess. Century tells me that they cannot trace any calls back to 2013 but if I pay R900 they will s**** the rest but I need to call head office. Head office tells me they will s**** the R900 as i explained i did NOT breach contract. Apparently this never happened and the manager asked me to pay R900 and they will activate my membership again. Instead my account is handed over to MBD attorneys who are the most irritating people ever with another enormous amount of almost R3000. Disgusted at the service but apparently I am not the first person they try and *******. Whole year the refused to give my free Vitality Gym membership with them rather playing billing games with me. Discovery unfortunately cannot assist as it's a Virgin Active issue. Disgusted will definitely go to the competition!
