Unprofessional and rude behavior - Consumer Complaint for PEP STORES

I would like to file a complaint against one of your employees Busisiwe Sithole from your Ulundi branch King Senzangakhona. My mother was trying to send through a parcel for me. She was then asked to give a store number to which the parcel is being sent to. I then asked to speak to her over the phone to explan I don't have such information, surely she can acquire that from her side. Even suggested she contact your customer service she is your employee. To which l was told people like me can never get help who think they know too much. My mother had to go back home without any assistance. She had such attitude towards me. I was really disappointed as I gave always used your paxi services and I have never encountered such problems.
