NO SERVICE NO RESPONSE NO CUSTOMER SERVICE

I have been begging Autopage to sort out my account that has gone horribly wrong since they took my contract over from Nashua since November 2014. I have mailed them and phoned and begged and I have no response. My service has been disconnected and re-connected and now disconnected again. Nobody responds to any form of complaint even with their own ref no\s. How do I get my line connected if nobody responds and nobody is willing to give me the e mail adress of a supervisor or someone with authority. I want to cancel my contract and deal with Cell C directly. I did not ask for Autopage to take over my account
