Formal Complaint for unpaid reward

On 31 August 2020, I bought a product for R1999 which was a vitality product. At the time there was a vitality booster of 50% a,d I was supposed to receive such. The amount was not paid on my September cycle. I made an enquiry reference numbers , and below are the enquiries made with no resolution to date. My challenge is when I request feedback from a Supervisor (Uzer) who never ever bother to call me. Also the Call Centre agents who look at the complexity of the case and decides to cut the call. This is highly an ill discipline. This morning, I spoke to a person, not sure if his name is Edwin, shortly after 8am, and upon requesting to be transferred to Uzer he said he doesn’t know his extension, and when I said he must then find out he asked me to hold, then he dropped the call, which I expected, from the experience that I am encountering with the Vitality team. Please see the below figure with the exact details.
