Refused refund from Makro

I bought something online from Makro. I called them and asked if I could cancel the order as it would take longer to deliver because of public holidays. They said its not a problem they will refund me within 2 to 5 days. This was 2 weeks ago. I called in to ask why do I still not have my refund they said there must be a problem with my bank. I asked for a proof of payment so I can query it with my bank then if that's the case. They just gave me the run around till today.
