Unacceptable Service From Telkom

My mom wanted to upgrade her contract phone she has with Telkom. I went with her to assist her as my mother is rather elderly. The first shop we tried was the Telkom Woodlands branch in Pretoria. Everything seemed to be going well until they had to scan her fingerprints. There was constant issues with it, and the more we asked the consultant questions regarding it the less it seemed like he even knew what we were asking. I asked him to try a different scanner as the one seemed not to scan the prints correctly. He wouldn't do that. The more we explained to him that my mom's prints might not be on their system as she hasn't been scanned in the past, the more he argued with us. When we asked him with what company he is trying to compare the prints with, he couldn't answer this either. We finally left and thought we will go try the Menlyn Mall branch. The service here was absolutely poor as well and it was to us like they had no priority to their clients or to client service. The consultant at the Menlyn branch told my mom that her phone is fine, why does she want to upgrade. Which made my mom feel like he saw her as nothing more than an old lady he doesn't need to assist. He also tried to sell her a completely different phone than what she was interested in. When he said the one she wanted isn't in stock, it took 3 attempts at asking him when they will have it in stock again before he got to the point. At this time, we were just fed up with the terrible client service we've had recieved at 2 different branches on the same day. When we got in the car and left, my mother broke down in tears! This is really unacceptable.
