Jock dog food competition seems to be a hoax

Entered several times into the Jock's latest R500 000 cash prizes competition. One of my sticker numbers were successfully as per their confirmation Whattsup, I was informed I won R1000 and would receive a confirmation message. I received said message with the input pin for claiming the money from any Standardbank autobank machine using cardless transaction and I would receive a pin shortly. Its been a view days later I was never messaged with the pin needed to draw the cash prize.
