Refunding of funds

I placed an order with Makro shopping online, on the 9th April for essential items to the value of R1209,00 and was assured that the items will be delivered in 3-5days. My order number is MAK*** In 7-9 days, I made a followup about my order as it had exceeded the estimated delivery days and I was referred to Makro in Springfield. I immediately phoned them and was answered by a rude, non helpful employee who told me the courier services had my items but she refused to do a followup with them. I made arrangements to obtain these items elsewhere and therefore proceeded to cancel my order with Makro and assured I’ll be refunded. I have made a followup with them practically every week until now, I have not received my refund and it’s almost a month.
