Makro Online Support is Makro Offline...

Makro Online has meant nothing but frustration and trouble to me. After I logged a refund request for receiving inferior products on a double order, I have only been refunded half the money. We are now 7 weeks away from the original order date. Both items were returned to Makro in pristine condition since I had no use for it. It was outdated and digitally incompatible. They did agree that it was refundable and even sent me a statement showing my payment of both items and their refund of only one of the 2 items. They can't understand that they still owe me the rest of the money. What to do?? I'm at my wits end. How can this be so difficult? The same Takealot order took only 48 hours to deliver.
