Horrible Experience with my Agent Bafana and Wonderpark gym

If I could give a zero rating I would, I took up a gym membership for myself, my partner and my daughter. Upon sign up they told us we would pay 50% for 3 months. Our agent was Bafana, Virgin Active Wonderpark. Month end comes and the debit order is more than the amount that was stipulated and turns out the 50% over 3 months is divided. Ok we ask Bafana to thoroughly explain and he continues to say we need to pay R320 for he 1st month then it'll continue to be R180 of the rest of the 2 months. I asked him to send this to me via email, which he didn't. But he assures us it'll be R180 for the months following. I tell him I will allocate that exact amount for the debit order and he says yes our memberships will be R180 each and R110 for my daughter. The 1st comes and the debit order goes off buy bounces because instead of R470 the amount debited was R740. I ask my partner to find out while at the gym and he tells me that Bafana says because last months debit order bounced we lost the 50% discount. How is that out issue when it was the agents fault for not explaining that the 1st debit order would not be 50% but 30% off I think as he vaguely explaining after we complained and went to the branch. I am livid, disappointed and disgusted with the service from Virgin active and I will escalate it with the ombudsman. It is ********* and dishonest how their agents conduct business. They evade questions and don't want anything submitted in writing. The manager included. Truly sad what this franchises reputation is being reduced to, I will be taking further action. When I was taking up the membership they where enthusiastic and even willing out the forms for me, now that there are problems they couldn't be bothered to give me a second thought.
