MTN worst expereince

MTN has done the most terrible thing to me affecting my business, with the number that I have used for over 10 yrs, I joined their MTN skhokho promotions since I own a small business. They blocked my prepaid number saying they are investigating *****?? if that's the case why don't you call me and we solve whatever issues you have with my number, now I am loosing customers because of them. call them several times to fix this but its still not fixed.

what a bad experience
