Bad service Telkom Maponya Mall

I am very disappointed at the service we got from one of the consultants at Telkom Maponya Mall, she was doing a simwap for my grandfather and the sim card was not working, we went there and were advised to go to her table Her name is Lebo, she was seating at number 6 I think, firstly she was chewing a gum, she looked at us once and dismissed us to go seat down without hearing why we were there, when she called us, she was talking to my grandfather while chewing and was very rude and gave us attitude, my grandfather asked me to tag along because the first time he went there he was given attitude by this girl She must fix her attitude and treat customers with respect and dignity Doing sales with that attitude? And chewing a bubble gum like you're talking to your friends Are you aware we lost how many clients and money because of someone who wasn't paying attention when doing her job
