MTN DOES NOTTO ACCEPT THEIR SYSTEM PROBLEM

***8, MTN billing is incorrect, I decided to follow closely and checked my data balance regularly. MTN balance enquiry kept on indicating that I had balance of data and promotional data left. However the balance enquiry has been stuck on 1.09 GB for days and when I use internet between 6AM and 12AM, the normal internet of 1.09GB is not moving, the one that is depleting incorrectly is the night express. I have tried over and over to address this with MTN but their *********** consultants ignore my emails or not answer questions asked. I have given and kept print screens evidencing this system error. I have asked for management to intervene but they are refusing to engage them. I will have no choice but to report this to ICASA if MTN is falling to rectify their system error. I have more than enough evidence which they are ignoring. Most of my initial emails were ignored for weeks without any reply.
