Sandton City Bad attitude of sales staff

I would like to bring to your attention the horrible behaviour and attitude of the two ladies who were on duty in the Sandton City store on 6 September 2019 at 18:45 pm. While he very kind gentleman was helping me make my purchase the two store assistants were rowdy and laughing while the poor gentleman was trying to hear what I was saying. To add to this, the one lady then said to her colleague that she should be louder because I have an attitude. I did continue with my purchase as the gentleman assistant was very kind and professional.
