3 months of waiting for proper feedback

I decided to join momentum's multiply loyalty program seeing that I'm a bankmed client, and they had this offer off 80% discount at VA gym. not up to, but guaranteed 80%. after speaking to the call centre agent, two different people to confirm what my monthly gym membership would be, it was confirmed I would pay R148. then the debit order went off and the amount was R240, then I called again to asked why there was a difference, then I heard something else that the 80% is capped at R500 for bankmed members, and my original fee at the gym would be then R740. Fair enough, I spoke to an Suresh Moodley. I wanted these recordings where I was said it would be capped at R500 discount. Now he promised me this disk on the 28/05/2015. the 28/08/2015 I emailed him again asking where the disk was. till today I'm waiting. I know what I heard, So if there was said the amount would be capped, I just wanna hear this again. but nothing. I popped him a email this morning to asked the courier name and tracking number, but no response yet, so who is lying here? Can I get some feedback ASAP.
