Disgusting Service From Woolworths

I’d like to log a complaint against a staff member at the Woolworths Food store at Boskruin Village (in Randburg). I got to the counter to pay for my item and thought I had forgotten my rewards card at home. So the cashier, SIMPHIWE, scanned the item and then I actually found my rewards card in my purse before making payment. So I asked her to swipe my card in order for me to receive the 10% discount off the item I was purchasing. She was extremely rude and impolite about it. She shook her head whilst proceeding to call the manager and assist me. Whilst I was standing there, she was telling the manager in her own language (whilst still shaking her head abruptly) that she had to reprocess the item because I had first told her that I did not have my rewards card but then “all of a sudden” I found it. She continued bickering to the manager until I made payment and proceeded to leave. First and foremost, if I had to do to her what she did to me (i.e. speak about her abruptly in my own language to my manager whilst she was standing there as a customer), I would have been immediately classified as ******, right?! However, for her, it’s perfectly ok to treat customers that way as if she is doing me a favour. Maybe she forgets that it’s loyal Woolworths customers like me who basically pay her salary. If it’s such an effort to offer friendly customer services to us “paying customers, then leave and allow Woolworths to hire people who actually WANT TO do their job effectively! This is the first time I have experienced such disgusting service from that particular store and frankly I will never go back. Also, please let your staff members to be careful when speaking about customers in their language because some of us actually understand the language...very well.
