Bad service

Today I went to medirite west gate mall. I was helped by Hlumelo Baai, she was so rude to me. I have leg injury and she said she will give me Veltex and I told her that another lady said these pills are for blood absorption and she said to me "so lady what do u want me to give you" with a very bad attitude. And I said to her don't be rude to me ,you are suppose to explain what are the pills really for not ask me what I want you to give me . I asked to see the pills and she gave them to me, as the was not much information in the container , I wanted to google the pills and she said give me the pills back and I told her that as she failed to explain the pills Im looking for my phone to google what the pills are really for. She demanded that I give her the pills back and she wrote the name of the pills in the paper . after I google I asked her to sell me the pills and she did with a bad attitude . please educate your staff on how to treat costumers .that lady was really rude . I was very angry and hurt when I left . that was really a bad service
