Very unhelpful staff

My elderly mother went with my son to the vodacom store at Carnival mall. They stood at the technician. The lady was sitting scrolling on her phone on her wattsapp as her phone was lying flat on the counter, this is not the first time this has happened, the last time it was the same and we asked for the mananger, he asked her to please assist us. She was not very friendly after us reporting her to the manngar. Today my mother and son stood there for for more than 10 minutes to try to find out why she cannot make any calls the techniciam was scrolling on her phone and she did not look up from her phone. My son then asked the staff at the door for the mananger and was told to ask for him in the store. My son and mother then left as my mother is 83 years old and could could not longer stand and wait. My son then took my mother to the Hub to pay her account. when my mother got to the HUB my mother fainted from standing so long. The manager of the Hub had to fetch her a chair and got her a glass of water. My son left my mother at the Hub silling on the chair and went to move the car closer. My son went back and the staff showed him who the mananger was, the manager was standing outside. He listened to the story and then wanted my mom to walk back to the store in her condition. The manager at the Hub arranged a wheel chair for my mother and my son took my mother home. Is this how the elderly are trated at your stores. this is totally unacceptable as my mother is in alot of pain after the fall. This is the branch at entrance two next to Edgars
