Rather use robots in call centers than speed script reading agents who lack people skills!!!

Called the call center for assistance regarding a promo. The store was unaware of the promo and the app didn't allow me to place the order with the specific store - which btw is the only store in JHB North that we could have got this promo from (FYI - a National Promo). The call center agent spoke terribly fast & regardless of the fact that I had a question & was still talking, he just went on and on over my voice and asked me personal questions without informing me that he needed my response to verify me.. and BAMB!!! He says go send an email from the website! I didnt even hear the website coz he sang it to me! Like ***!!! Customer experience sucks! +-15min of MY call to only verify my user ID/account, and then direct me to a website. I requested to speak to a manager who spoke just a little slower yet both lacked 'people skills'. I was not happy at all, South African call center agents can nag the hair of my head with their marketing calls but they have people skills and can empathize with the person on the other side, but these guys I spoke to ... no ways, I am so not happy with my experience and I still have an unresolved issue!
