Poor Service from Shadows Gateway

I received a POLO Shirt as a gift. It was small and I wanted to exchange it for a larger size at the Shadows Gateway store where it was purchased. It was in the same package with the labels, barcode, Tags etc. still on it. What I received from Shadows Gateway was a most unpleasant experience. They refused point blank, saying that I needed a receipt, despite me telling the rep that it was a birthday gift and it is not appropriate to ask the person who gave you a birthday gift for a receipt. All I wanted was to exchange it for a larger size, NOT a refund. He point blank refused saying that this was the instruction he got from his manager, a person by the name of Nazeem, who was nowhere to be found. One would never get this type of service from reputable stores like Cape Union Mart or Woolworths etc. This is the problem one encounters when dealing with Mickey Mouse stores.
