DStv AT IT AGAIN!!!!

I have been dstv's loyal customer for quite some time but i think it's time i part ways now. I have won a reward and was to claim in the 10th of October but i wasn't able to apparently because 1. I didn't contact them to claim (as if i was informed to) 2. My prize has expired 3. I made a late payment and even lost my stars as a result. I have been looking forward to the prize for a few months now and it has always been there on the App even though i sometimes made late payments but all of a sudden when i have to claim, the prize ia no longer there?? Dstv??? How come?? And it looks like the consultant assisting kept on looking for loopholes in order to come up with excuses on how my prize is no longer there because they kept on saying this after that. I'm extremely disappointed that i'd rather cancel my subscription than to be ****** like this!!
