Centurion Mall MTN

I have never been so insulted by a sales consultant at Centurion Mall, i was there seeking answers on a contract i had opened on the 8th of Sept....being the 25th on Sept they sill have a system error on their debi check on they're side...long story short not him saying i will never get help with my attitude nor will he assist...out of no where i don't recommend going to this store people are rude beyond and him being a male to say that in my face like im some child, further more with customers in the store and stuff watching i am sending complaints to MTN but no respond goes to say about their service n the people working there.
