Pathetic Service at Norwood Mall CellC

I had the worst service possible today (17/01/2021) at Cell C Norwood Mall branch. I had gone to do a sim swap because my phone was ******. I was told to complete the necessary forms, listed 5 numbers needed, the consultant immediately told me they weren't on the list of last dialed number before even checking properly. I told her to check again but she became aggressive which in turn aggravated my partner and I. Only to advice after a few exchange of words that she had recognized 2 numbers on my list. If your stuff does not know how to deal with customers directly they should be flipping burgers at the kitchen and no direct contact with people at all. Secondly why not change the security questions to something easily memorable like childhood friends or first pet name because the last 5 numbers just ain't cutting it. And just with this treatment I have moved to another service provider who don't pose ridiculous questions just to prove the number is mine. I am expecting an apology for this.
