Shoutimg at customers

I have been trying to get hold of the store but their number is not workong. On the 30th of October i went ro Mr Price clothing festival mall and bought a tshirt/*** there was no problem it was around 17h30 until we went to the cashier with my daughter. My daughter first started greeting the cashierand the cashier did not respond, i greeted her she did not respond my daughter greeted her again thinking maybe she did not hear to our surprise the cashier said she heard the first and second time and she did not respond becasue she is tired of greeting customers and mind you she did not speak softly she shouted at her and the cashier's voice has this big tone, she told us that we shoyld vack off because she did not want to be greeted she is tired. I asked her why is she shouting at my daughter and she told me what must she do when she is tired. I tried looking for her name tag she was not wearimg one even the receipt does not have a name. The receipt number that was issued is *** my daughter was so traumatized about the ladies response as she has never experienced such. She swore never to put foot at Mr Price because of this lady.
