MTN Consultant making jokes of me

I walked into the MTN store in Killarney Mall and after 1 minute a consultant called Lusanele called me to help I got to the counter and said I need a car charger, he kept making like he cant hear me after repeating myself 4 times he joked around and didnt take me seriously I am not happy with the treatment, I work on time so I walked around the corner to Cell Care 1 and was helped quickly and efficiently
