Bad Customer service and Disrespectful staff

Went to Cradlestone Mall yesterday afternoon to buy a few things when I got to the tills got helped buy one disrespectful young girl who pushed the swiping machine to me then I asked to talk to me, then she said I must tell her that and she screaming at me, she went on telling me not to come with my issues,I then asked why is she shouting but at me but then went on telling me that she can say whatever that she wants to say and she call the Manager if I want her to. A light skinned lady with short hair who also works as a cashier was called to be the Manager yesterday,,she asked me what happened the same rude girl responded but I could answer…the Staff is annoyingly Disrespectful.
