My MTN network services keep getting suspended.

My MTN network services keep getting suspended. This has happened twice in the past month and there is no reasoning behind it. I currently cannot make any calls, send out messages or access the internet. <br> I tried calling the call centre but they are currently striking hence the call centre is closed. I went into The Eastgate MTN and no one was able help me. Their excuse was that they are unable to assist due to the call centre being closed.<br> No one was able to give me a reason as to why my services has been suspended or provide me with any indication as to when they will be able to assist with this. I am now currently sitting with a phone that is unable to make calls, send messages or connect to the internet yet I am paying VERY MUCH every month for this contract<br>
