Disgusting, bad, disrespectful customer experience

I was at the store on Tuesday during my lunch time to go buy some meat, there were long queues at the same time it was month end, thou I understand the situation because of covid 19, I then proceeded to go pay at their kiosk, when I got there the cashier by the name of mpho in a very rude manner went on to tell me I should not put the meat on the counter as it will mess up, I then asked her how will she scan the items if they are not on the counter, she the said I must hold on to the cold items on my hand, she said that with attitude even looking at me me like I'm nothing, I then called her manager it was a white lady either the store manager or floor manager rite there she told mpho to come her nerves down but mpho kept on lashing at me in front of the manager lady, then the manager went to attend someone els at another till living mpho serving me and busy talking back to me with attitude, I called the same manager again whome she said she will deal with mpho even thou mpho was busy going on... Such behavior is not allowed at the same time the company as big as pick n pay does not need such employees that don't respect customer.. I'm still sad about the situation and I wonder if this matter is being dealt with... I am a regular pick n pay customer but now I have concerns about their employees and how they conduct their training of customers service.. I'm not going to let go of this matter as it hurt me so much.
