Refund

I ordered a Samsung smart TV on VodaBucks store. Which I later cancelled the order with the company called Digital Planet then they directed me to call vodacom for refund as they are only dealing with deliveries only. When I try to call vodacom customers care it was a struggle as most agents didn’t even know how to deal with this matter and there is no direct number to VodaBucks that deals with refunds. I was told to email the proof of purchase and the details of what I was buying which I did email to customer care, and there was nothing after that. The lady from customer care told me it will take 7 to 14 days before they get back to me but it been many weeks pass by there is nothing all I need is to be refunded my money back. I don’t understand what takes forever and they are not even communicating with me
