Terrible attitude and attack from Makro Staff members

I am very disturbed by the service I received from one of your staff members, Mary Modiba at your Woodmead branch. I only went to buy a gift voucher at the multimedia counter and she gave me the worst attitude and giving me and while still waiting for her assistance she and her colleagues went to their corner to discuss about me and start laughing. When I confronted her about her unacceptable behaviour she gave me attitide, staring at me and talking to her friends in a language I could not understand. I asked for her name and she still refused to respond until I asked her colleague who came in during the conversation and told her to apologise for the treatment to which she still refused and continues to now shout at her colleaugue in the language. I am really disturbed by this and do not think makro should have stuff that belittles their customers.
