MTN Gandhi square needs training and take customer seriously

My Sim card is still not working. I am truly disappointed by the service given to me by MTN gandhi square the employees do not have their name tag on that is one of the reasons the give us bad service. After been with MTN contract for 6 years full am ready to move to another network provider the staff have their own work ethics which put customers last. They did not register my Sim card for a Sim swap I called MTN and tlthe ref ********** 57 now I have to go back to gandhi square which is transport and money and time being wasted. Kindly give staff training and customer treatment.
