THE MOST ********** SERVICE PROVIDER!!!

<p>I have been using MTN network since I started using a cellphone and it is to my disappoinmnet that everytime that I have a Rand value amount for airtime it disappears with no warning. Irregardless of having data bundles or NOT! THIS is an ISSUE i have raised with them serveral times and all I am told is "INTERNET USAGE" WTH? I am honestly changing NETWORKS!! The only conversations im having at work with my colleagues with the same network users is this matter. AIRTIME DISAPPEARING AND FOR THAT WE ARE ALL CHANGING... </p>
