Disgusted by Service

I am very much disgusted and dissapointed at the service that I recieved today at Woolworths V&A Waterfront. Having being a customer for over 10 years I am disgusted for having being loyal to such a pathetic retail store. I called the store today just after 5pm requesting to return items that I had bought over the weekend. I was told I could come in the store so that they can assess if the items were in a saleable condition. I get to the store just after 6pm, Tahirah approved the return and advised that I should take items of the same amount. After looking around the whole store I find 2 items which I needed then went back to customer service for the exchange. A lady that assisted me at the till advised that she would not be able to give me whats left on a gift card. To my surprise I then request a manager (Unathi) who advised that she would not give me a gift card I need to look further, at this point I could not understand because there was nothing I could see. I stood for 20mins then another manager by the name of George gave me attitude telling me that I will not be given a gift card its either I take things for the full amount or they will give back my items. At this point I was very much upset because it still does not make sense aa I was now forced to take things that I did not need I mean the gift card was going to buy at Woolworths after all. It came as a shock to me beacuse last week a Muslim Colleague of mine exchanged an item in Cape Town CBD and had no hassles at all the change was given on a gift card and he used that gift card at woolies food. Now upset is an understatement. I am not sure how to take this but I know for a fact that I will never set foot at Woolworths V & A after today.
