Humiliating experience

Yesterday I went to do my shopping at Pick n Pay Bellville : Middestad at around 17:00. The teller was so horrible , disrespectful and rude and lacked customer care service s****s . She practically asked me to my my own groceries because I only purchased 1 bag from them and had the other underneath. I advised her that I want to check my groceries because I do not want to exceed a certain amount but with pointed her finger at the teller screen and said " you must look here". I asked her why is she asking to pack my own groceries and her response was " you decided to keep your bag". The first bag I purchased was not even packed. She only put in Jik, Body lotion and Raid plus her response was when I asked why didn't you at least fill this back " I didn't know whether to mix the things with your groceries or not". She didn't even ask. I cautioned her as an elder and advised her that she is being very rude but continued embarrassing me in front of other customer and actuality I felt humiliated. She continued to undermine me by asking the next customer after me as to where to we get the pick n pay vouchers because it seems like everyone is using them. The customer explained that she is a student and that's how she got hers etc. I'm not a student and as a pick n pay employee she should know her own products and ways to get them. She even said to me " hurry up sisi and clear the till because I need to scan other customer's groceries". I continued to caution her but she didn't even listen to what I was saying. Getting to work today and explaining the story, my colleagues also shared the same description of her and complained about her nasty attitude( one of them actually sweared at her). I'm highly disappointing that at this day in time with high levels of unemployment we still have people who practically goes to work to display such attitude, people who are very rude and sarcastic plus belittle others in order to make them feel better. This lady needs to be moved from customer care to either the storage or kitchen where she doesn't have to deal with customers daily or change her attitude because she is old enough to be my mother to possess such attitude and behavior. She humiliated me not only to other customers but to her staff as well because she was extremely loud when instructing me and created unnecessary audience not only for me but to make her self feel better maybe or to get praise from her colleagues.

I've been working in Bellville since 2012 and have been shopping at the same Pick n Pay but since yesterday, I'm highly embarrassed to even step a foot at that store because I'm sure the staff would be like " that is the lady Sis B dealt with" and would not even recommend my staff to go there again to prevent them from such humiliation and embarrassment. In the process I lost my voucher because I only made a purchase of R362 out of R500 voucher, I don't know whether I left it at the store or misplaced it because the only thing I wanted to do when I left the store was to cry. To me as a single parent I work hard to load the voucher with the little amount that I save monthly. Meaning that she didn't not only humiliate me, embarrassed me and belittled me but I also lost something with monetary value that feeds me and my child.
