No service for weeks cause MTN Staff r on strike

My services have been suspended from the 1 June 2015, even though i paid my account on the 25 May 2015. The call centre is not going through. I have been on hold for 35 min and counting. I am unable to make any calls or used my data. The voice prompt says i must call my service provider but my calls are being cut off. I know for a fact that MTN staff are on strike n there has been no communication to the customers. I even email customer service my proof of payment but i have not received any response. I have been calling the call centre for week with no response as my calls were cut off after holing for more then 15min
