Bad customer service

I went to pep home maponya mall store no 5555 to do a paxi drop off and I had the worst customer experience, the lady who was assisting me has the most awful attitude and knows nothing about customer service and she should go back to training, she gave me a device for me to select a drop off store, as I was doing that unfortunately I made a mistake as I on the call and the app had changed screen, I asked for her assistance and she said there's nothing she can help me with I already processed the drop off and I should leave the store, I asked her how do I leave the store without any Sms confirmation she said she doesn't know and there's no way of re doing the process, I asked to see the manager, she said I should go get the manager myself and she continued assisting her other customers while ignoring me like a fool, the manager came and asked her to apologize to me but instead the lady started shouting at me instead, her name is zodwa and I don't know how she is doing customer service with that mentality and behavior, her manager called head office and fixed my query only to find that the reason why I didn't receive an sms is because she deliberately put on a wrong number because she didn't want to assist me, if that lady doesn't want to work she should just stay at home and let others be employed, she is not doing anyone a favor by being there, I will never go to pep home maponya ever, and whoever goes there avoid zodwa or your parcels might even go missing
