Management passing the buck, bad service

I had an account with Virgin Active in 2008, I encountered financial problems and I was unable to continue paying. The account was written off and I was blacklisted on ITC. On the 28th of September 2015, I went to Meyersdal club to join as a member. I was told I no longer owe them and the file showed no outstanding amount when they verified with the call centre. This was because the bad debt was written off seven years ago. I then proceeded with the new contract. To my surprise, a day later after I had payed, I was told that I owe them and I had to pay the outstanding amount. I was told that the new Sales Manager, Shepherd had reinstated the old debt. I know that this was ********** and *******. By Law, the debt gets written off after 3years, and the ITC takes up to 5years to clear a person's name against a bad debt written off. I told them I wanted to cancel the new contract, until they fix the problem and they claimed to have reversed the money payed, which is still not showing into my account to date. To make matters worse, Shepherd refused to talk to me when I was at the club, and he also refused to take my calls when I tried to get an explanation from him. I need answers ASAP
