Missing Change

I am incredible shocked by the service i received from Christinah Mothapo. I bought Bio plus and paid 200zar cash. When she gave me my change it was short of R100. When i arrive at my store i realized that my change is short of of R100. I went back to pick n pay together with the slip and showed her that my change is missing telling from the slip that i gave her R200. She gave me such a horrible attitude and grab the slip from me and ask one of the colleagues to check at the camera. We started exchanging words. She has no manners at all. And some people are talked with in store they told me that shes got an attitude. I refuse to be treated like piece of **** by Christinah. How many of your clients has she gave them stinking attitude?? how many of them she has ****** them from giving them their change if they don't check it? she is committing *****. I believe i am not the first and not the last for her treat the way she treated me and try to commit ***** and when i asked for a my change nicely she gives me stinking attitude. The camera proofed that i gave her R200. Did i really had to go through this ****?? Please sort out nonsense she is really degrading Pick N Pay Values.
