Stinking service Shoprite Sharpeville

I went to shoprite in sharpeville today I was treated with bad stinking service I presented my code I received for competition but the cashier was rude she said I hit her witth my phone,which I didn't do even the cameras can tell she didn't know what the code is for when I speak she kept on responding to me with bad attitude that I bring my problems at her work I'm old for nothing.i am really said that Shoprite doesn't know how to teach thier staff what is TCF treating customers fairly the customer service was stinking I will never shop there anymore
