Buying sim Cards

I went to Pep Cell in Quagga Pretoria West to buy just 2 Telkom sim cards, little did i know that my afternoon will be completely changed by a cashier worst attitude which was uncalled for. She requested my Id and proof of resident, which i gladly handed to her. As she captured she read my street name out loud, i responded by repeating the street name e.g she said "Dilan" and i said "yes Dilan" Then she said to me she was just saying it loud but she does not need my help as she can read. I was slightly offended by her response and i made her aware that i was not fighting, then she started asking me who told me that she was fighting. The lady was completely rude and didn't even consider me like a person. It seemed to me like i disturbed her from her confort zone by coming to buy cheaper sim cards whilst the store was very quite, maybe she could have had a better attitude if i was buying a phone or something big. Kindly follow up and keep me posted
