the staff member knows how to handle irate customers

I went to the store MTN at the design square Brooklyn Mall on the 11 of October 2019 to collect my phone which was booked in for repairs. I always go to the same store, but I was assisted by a lady named Thato, it was my first time seeing her there. I was very upset because of the service I received the last time I was there, but Thato knows how to handle irate customers. I have never received such good service at MTN before, I visit the store every month to pay my phone that is still under warranty and the service is always bad. I just want to thank Thato I was emotional because of something that happened in my life and just the service I received from Thato made me feel at peace.
