Zero customer service with voucher for DStv rewards programme

I signed up for the reward programme on the DSTV app more than two months ago. I claimed a voucher for R100 off DSTV installation. I then sent a message on Facebook Messenger to DStv on 2 November 2020 enquiring how to redeem the voucher since my installer (who said he is accredited) was not aware of the voucher system. They then asked for the installer's details that day which I immediately provided and was advised that the matter will be escalated and feedback would be provided.

On 3 November 2020, I asked for a follow up and explained that I wanted to arrange installation that week still. Since then, I have submitted numerous follow up queries and was told that my escalation has been prioritised many times since 10 November 2020. After a further follow up on 2 December 2020, they asked me for a screenshot of the reward I claimed which I dutifully provided. I was then told my matter has been re-escalated and that I would receive feedback very soon and that I should please be patient. That was on 9 December 2020. I have had no reply since then. I am more than happy to provide the full Facebook Messenger written conversation, detailing what I've gone through.

Now, it has been more than two months since my initial query and all I can conclude is that no-one at DStv has any understanding of how their reward programme works and no-one is willing or able to assist me to resolve this matter.

I so wanted to install DStv into my son's room two months ago so he had it for the school holidays and all I am left with is total disappointment at the complete lack of customer service and disregard I have had from DStv.
