Makro delaying in paying refund

My purchase on the Makro online store had begun well. I purchased a PS4 with a free game. However, when the delivery had taken place, the game was not delivered at the same time. After more than two weeks of waiting, I returned the PS4 as there was no game that was to be delivered. The Alberton store only refunded me for the PS4 as I did not hand in the game that was not even delivered to me! Wow! The store said that they would pass the credit for the game when I received the game and returned it to the store. The challenge is that I have not been refunded for the PS4 initially returned into my credit card. This has been many weeks now and my attempt to call the call center and email the help desk has not resulted in any action or refund being received. Makro has all the goods back and I have not received my refund.
