Nobody available to take my call... EVER?

I have been trying to call MTN's contact numbers since the end of February because my contract has come to an end and I wish to cancel it. EVERY time I have called from my mobile AND from a land-line number the call literally is disconnected because of how long it takes for someone to ANSWER the call!!<br> <br> I understand that call volumes can get really high and that is the reason why I call at different time of the day, This just illustrates how *********** their Workforce Planning department is if they can't manage their call volumes. Now we approach May and I STILL have no joy getting through to anyone! My contract has ended, the phone is giving me numerous issues and I can't get a contract elsewhere until I cancel this one!!! <br> <br> I need a manager to call me back or email me to tell me my contract is terminated and they BETTER not charge me for this new month!
