MTN JABULANI MALL POOR SERVICE

I went to MTN to do a sim swap for my son as the number is registered in my name after failing on the self service, when i got there for the First time they told me that they only service sim swap between 9-11am, so i was late, went back a few days later the very same consultant told me that i had to come with the child as there are questions they have to ask him, i asked them why didn't they tell me that when i was there the First time, the times they service sim swap the child is as school, why are they acting as though the shop belongs to them, they choose when to service customers and not, and yet the times they're choosing are times affected by load shedding, they didn't care and i left. Im not happy with their service at Jabulani mall.
