Poor customer service

Such a bad service I got from the Sandton City store. There's a lady there, with a birthmark on her forehead. At first, she could see that I needed assistance and yet she didn't come to me, there was another lady helping a gentleman at the till. Secondly, when I was asking about a certain pair, she moved away behind me while she wad talking. I had to turn and tell her that I can't hear her and I could tell that she wasn't interested. When I was paying, I asked about the return and/or exchange policy, to which she had no patience and explaining clearly to me. Again I told her that I can't hear and understand her and I could tell that she had no interest. Even after I had paid, there was no usual 'Thank you' that one gets from the staff/personnel after helping you. I'm SOOOOO DISAPPOINTED that I had to experience that when the customer before had a pleasant transaction. I had to ask myself if my experience was based on my gender and/or race.... That's truly IRRITATING and DISAPPOINTING in this day and age.
