fed up

1st march 2014 I took out a gym membership contract with virgin active.i attend kick(aerobics)classes on Monday,Wednesday and Thursday 6pm-7pm.the problem started when the music would stop while we busy working out.the problem continued and our then instructor told us that he will no longer be conducting the class as the music system thing is demoralising him,we raised the issue with a guy by the name of Sipho who told us that the issue would be solved as there is a club in the suburb that would be closing down and that the music system would be installed in our club,Sipho also gave us leaflets to write our complaints on which we did,we were also told that we would be getting calls to receive feedback regarding the matter.No feedback was given until the instructor stopped coming to class like he did,we were then given a new instructor but the system issue continued.After calling their head office and a meeting with the club manger the issue is still not solved.Highly disappointed.
