************** and unfair treatment

On the 9th of August I went to Edgar's in Benoni Lake side around 3pm with my younger sister who had an interest in purchasing a pair of jeans. We went to the fitting room and a lady by the name of Happy told me I can't go in the fitting room together with my sister an I asked since when she said the rules have changed and I didn't mind I waited at the door few seconds later an Indian lady with her child comes to fit and to my surprise and frustration Happy told the lady she can go in with her daughter and I asked her if the rules only changed for black people or did she think we were gonna ***** or something and she started apologizing trying to make a joke about it and I was seriously offended and reported this to Maria who was the manager on duty at the time she promised to escalate the matter and get back to me but to this day I haven't heard anything from Edgars. Please assist as I feel that everyone should be treated with respect and the rules should be the same to everyone not based on a skin colour.
