1 person can save an entire company's bad attitude

I upgraded my contract and went to Mall @ carnival for a new phone. As usual they have no stock it's the 2nd time. I then went into lakeside mall had the contract upgraded and was not handed a SIM card as I should do that at east rand mall as I requested to move my contacts over. I get to the east rand mall branch across clicks and was advised to use the other store across Mr price as they don't have the machines for that. I go to that store and met with Johannes Viljoen. At this point I was really fuming and ready to hand in my phone and cancel my contract. What a pleasure dealing with Johannes. I didn't see him use any machines or software??? He was absolutely friendly and resolved all my worries and frustrations in a few minutes. He is an amazing asset to your company and should be a brand ambassador for MTN. I am disgusted with the service levels at your other stores. From so called **** service to absolute brilliance. Please find a balance
