Horrrible bad service my manager at Pick n pay Blue hill shopping c

I returned an iron that was malfunctioning which i bought late month at pick n pay and i received the most horrible service ever by a manager called Zandile. she told me she will not return the iron as she tested it on a piece of paper and according to her its working, she said she will send it for repair and she didn't even bother to ask someone with more technical skill to assist and she refused to even tell me how long it will take for the iron to be fixed and return(turnaround time). she was very rude and she never bother to call me for updates until I called Pick n pay again after two days and I was assisted by her assistant called Lebo who took her time to explain to me the process and she even said i am still under warranty Zandile was supposed to assist me and deal with the fault without inconveniencing me and she said she will ask Zandile to call me for feedback, Zandile. She has horrible attitude as a manager she doesn't even have pick n pay value. she let her junior colleagues fix her bad services. Lebo called me twice to apologize and made sure that i get feedback regarding my issue.
