YFM DOESN'T PAY WINNERS ON TIME!!

On the 16th of June, i had entered a competition ran by YFM and Nedbank,  i was selected as a Finalist and was called live on air, where they announced me as a winner of R5000, sadly til date, i have not received my money. I had to chase them for them to take my banking details. They told me to wait 8 weeks for payment to be processed, their Ts&Cs state that cash payments take 4-6 weeks to be processed its been 10 weeks now. I emailed them and they said they will pay me on the 20th of August, now they are singing a different tune, they telling me they will pay me on the 20th of September. They have lost a loyal listener, i will never ever partake in any of their competitions
