Dishonest and poor customer service

DSTV customer service are a bunch of ****s and *********** people, on the My DSTV App I claimed a reward for free 30 days dstv premium upgrade which has turns out to be nothing but a lie, after a seeing that the upgarde haven't happened I called customer service and they said within 2-24 hours I will called and the issue will be resolved , more than 24 hours later no contact was made with me and the issue wasn't resolved, I called for the 2nd time and I was told to wait for 4 hours and that I will contacted and the issue will be resolved, fast forward to 4 hours later issue is not resolved and still no communication is sent to me, I called for the 3rd time and no times lines, no resolution, no explanation can be given to me as to why I am being subjected to dishonest and poor customer service.
