Very poor customer service - rude staff

I had one a very unpleasant experience at your Woodmead store yesterday. My wife and I went to Kitchenique in Woodmead to purchase some Maxwell and Williams cups for a friend. The owner and staff were very rude and I refused to purchase from their store. We went to Home Etc instead. I bought the same 4 cups which which actually cost more at Home Etc - this was not an issue as I will not support businesses that do not treat customers well. After paying for them, I asked for a piece of gift wrap to wrap them myself at home as I did not have time to wait in the store, plus it was load shedding, the store had no electricity or backup power and it was getting darker. It was already so dark in the store that we had to use our phone flashlights to see the items on display. The assistant (Joyce) said that she cannot give me the gift wrap to take away, but she can wrap it instead. I didn't want that. The second assistant in the store told her that it is fine and she must give me a piece. She was so rude and arrogant and complained bitterly in zulu, thinking that we cannot understand her. She said that she is going to phone the manager to tell her about it. The second lady (I didn't get her name - she previously worked at The Glen Shopping Centre) kept telling Joyce to stop it, but Joyce went on complaining about us as if we were not there. She even told her that the manager is not there and that she is in charge and authorised it. I told Joyce that she shouldn't argue with customers and speak badly about them - in front of them. I told her that her Head Office will not be happy about her behaviour - she challenged me to complain as she does not care what anyone says because she is right. We have bought 4 complete Maxwell WIlliams T&C's collections from this store previously. I will not be shopping there again.
