Prizes not forthcoming

I won a competition on Talk Radio 702 around the 15th of October on John Pearlman's show. I was super excited. Part of the prize was R2000 cash. I submitted my required documents on the 15th of October and I still haven't received my prize. They said their turnaround time is about 30 working days. Thapelo sent a mail saying the money would be paid on Friday 5 December, but still nothing! Also, when you phone 011 506 3200 (switchboard) nobody bothers to answer your call.
