Shocking customer service

I was at Shoprite Liquor at Tembisa Plaza on the 19th of January with my sister . As we waited in line to pay for the items we intended on buying which also took very long might I add. We uncounted grave disrespect and disregard by the staff there particularly the manager of the store. The staff were playing music loudly to an extent that we couldn’t even hear anything. The lady at the counter was calling us to pay and because of the loud music we couldn’t hear. The manager, started shouting at us in her language using her body language in an intimating way ‘saying can’t we see that she’s calling us, move with the line’. I addressed the way we were treated with the cashier assisting us that we are not happy about how we were shouted at and we would like the ladies name so we can report the horrible service. The cashier refused to provide it. We then asked for the manager, where we were informed that the lady who was shouting at us was the manager and she’s wearing a name tag. We asked the manager for her name as she was actually not wearing the name tag as we were informed. She refused. She even refused to apologies. I am shocked to see such and have never experienced such lack of leadership and customer retention qualities. I would recommend no one to the store. In fact it just needs to be shut down entirely. Shoprite just hires anyone without checking whether they are fit to actually do the job
