Poor customer service

Went to the store @ carnival mall today to get my mother a new phone was assisted with the best service that i have had in a long time by the sales person however the device that cuts the cut outs to do the gell screen protectors was not functioning properly and i was told that i can still get it done by their other store (vodacom chats) whent there only to find one guy in the store and he was already assisting a client after a while of waiting a lady appeared from the back i stated that i was told to go there to have my screen protector put on there for both my phones whereby I was told that they can't assist me as they can't work the machine and the lady who can is @ clicks and that we should wait for her or come back later when she is there. I told them that i needed them to be done as i have other appointments to go to i then had to walk all the way back and wait for them to help me back at the other shop since assisting clients was not a priority there I then waited as they fixed the machine to assist me they really put in an effort to get it done for me back at the first shot I don't have time to stand and wait for people to assist me when it suits them i chose to go with vodacom as they have provided me with exceptional service over the years this was an utterly disgraceful and poor service that made me feel like my business is not welcome
