Sphesihle Sangweni

I went to Shoprite hillbrow today looking to buy a combo for R199 (5kg flour, mealie meal and spekko rice. I got rice and flour but there was no mealie meal. I went to manager on duty and asked asked for rain check. I told him let me take what is available and he must write a receipt for me to come get mealie meal later. He told me he can't assist me, (Siphelele Sangweni). I told him this was done for me twice before and I have been buying from same Shoprite since 1998. He bacame rude and said the Shoprite paper says while stocks last. So he does not have what I want and he can't do anything. I told him but your paper says offer valid from 7th October to 20th. He went on to in shot say how stupid I was. He does not have customer service, no care no empathy. He treated me like am not worthy and was very arrogant. I told him I worked for Call Center for 15 years. FNB, VODACOM, CREDIT POTFOLIO MANAGER AND DEBT COLLECTOR. He said he did not care. Yes is a young man but given that opportunity at his age spells no experience. This was highly the worst ever customer service I have had. I had to go to another Shoprite to ask for a phone to call. The guy even refused to write his name and surname. He refused me a pen and a piece of paper. He told me to remember his name by heart. When I got hold of paper and pen he was so arrogant that he said I will give you the number for regional which is ***. I called and regional manager picked and I explained the story. I gave him my number and he said he was going to call me back for feedback as I asked him to sort the matter and call Sphesihle Sangweni to order. He since also have not called me. What is this?How do you teach your employee? This is a very sad painful experience.
