Bad attitude

I was at jet on 20/10/2015 to do a replacement card, I was assisted by Gloria who was so rude to me. She told me that they don't do replacement and she asked what happened to my card. I told her that my card got swaped with my sisters card and I will only see my sister in december and I want to purchase some stuff. She told me that then I need to wait for my sister. She also told me that my account is even behind with R600, I told her that my account is up to date the she insisted that it is not in front of customers. I felt so disrepected and embarrased. As far as I know my account is up to date and she had no right to shout at me telling me that my account is even not up to date. Gloria need to learn to treat customers with respect. I need explanation on how is my account not up to date, I need Gloria to call me and apologise for treating me the way she did. She is dragging down the name of the company. Disrespectful old lady.
