Jet_Maponya_Customer Service Nightmare

So I went to Jet-Maponya Mall yesterday to exchange my nieces shoes and I as I arrive at the till the cashier tells me "Uzobizwa" With an ample amount of attitude of course,I rep**** with a "sorry? and" she repeated "Uzobizwa" and I responded with I came here because I had already heard a "next" otherwise I wouldn't be standing here. As I decide to Walk away a male cashier (Nkulee) asks that I don't not go back in the queue and She asks him who called me and he then says it was him,he then pleads with her to do the transaction. So she does! I was so upset! My emotions were running wild! I don't understand how a person/ people can take their jobs for granted in such a difficult time and the unfortunate lack of respect there is amongst black people No apology, no remorse just attitude and just bad customer service, I believe the cashiers name is T. Ngubane according to my receipt. It would be nice if people actually respected their line of work and deal with their unpleasant attitude privately. Many people with the right attitude and energy are deserving of these jobs than those who just take it for granted. I hope the store will improve its quality of customer service. Thank you for this platform.
