MTN Billing is confusing

<p>first things first why does MTN have such useless personell at the customer care department?</p> <p> </p> <p>I spoke to a useless person called Siyabonga Zwane who insisted that I am a ****, he was not willing to listen to my issues and on top of all of that he was plain RUDE!</p> <p> </p> <p>Here I was wanting to invest in their share scheme but after that treatment and reading up on all the unanswered complaints on this website about the bad service and the works goodness that idea is out the window.</p> <p> </p> <p>My main issue is this why does MTN decide that your airtime should be used in a certain way I had airtime I used their supposed free aitime and now I have only R6 airtime left how on Gods green planet does airtime work on the MTN network If I can just have that explanation I will be very happy. Do you guys perhaps use some very complex algorithms that require 4th year app**** mathematics to understand or what I am confused.</p> <p> </p> <p> </p>
