You will enter a store but leave emotional drained because of bad attitude

I was assisted by a lady called Mashadi from Pick n Pay at Lephalale mall, horrible attitude. Horrible, horrible attitude. Firstly she made me wait when there was no que to finish whatever she was doing without consulting me, I greeted and she did not respond. Eventually when she decided to respond I told I was offended because I greeted twice and she did not respond, she told me she was busy and when she is busy she concentrates on one thing, mind you there is not client at the till. She told me she does not need distractions when she is busy, I really did not know that client at pick n pay are distractions. I told her that her attitude does not sit right with me and she rolled her eyes at me. I asked for her supervisor and that did not bother her at all, Mashadi whispered **** to me. She was told several times she was wrong but she continued to roll her eye at me confiming to me that she did not care even her superior forced her to say sorry which even she can confirm that it was not genuine. I was very disturbed that I have to come to the store and be served such bad service, such bad attitude, such a poisonous person. My experience was awful even her supervisor and packer saw that I was very distured. I told her I will report her but she did not care. It is really bad business to hire people who do not care about you customers. I shop there everyday, ppease assure me I will never recieve such bad service again. May Mashadi please apologise to me accordingly she really hurt my feelings, I am a customer in that store not a begger. My slip says chashier is Ngako Gran Sethosa but they called her Mashadi at the store.
