MTN Service????? What service???

<p>In June/July 2016 I migrated one of the lines on my MTN contract to prepaid, they kept billing me for that line. After numerous calls to resolve the problem, they disconnected my existing line(which was fully paid up) . </p> <p>I have now been trying for almost 2 weeks to get hold of someone in their legal department to get things sorted out, but no one calls back. Phoning every day, I have spent more than 3 hours in the last week alone on the phone to solve this. NO RESPONSE!!! </p> <p>I will not pay for a line that I migrated and they kept on billing!! They should fix the problem on their side and restore my profile as well because I have been a client for 15 years and has always been patient but I have now reached my witt's end!!!</p>
