Yfm and competition ****

Good day, I don't know if I should go public with this or can it be resolved quietly and quickly. I won a competition the McDonald's women's fifa world cup in July. T&C say payments will made between 6-8 weeks. Received communication that payment will be made on 20 October I sent through my banking details and still haven't received anything yet. Mathapelo was not taking my calls or responding to emails. Then on the 24th she sends me a email saying that the had system issues so my banking details were removed from the system so the new payment date would be the 20th of November. I smell fowl play here and if the error is on their side, why don't the rectify this asap. No communication was made before I started calling them over and over again and I feel like this is ********* and disgusting that a huge radio station could do this to their listners. Another strange thing was that I got an email from someone claiming that they are also waiting for the payment, however, I don't understand where they got my email address. So I am honestly not happy at all. They need to rectify the issue asap.
