Pathetic service, don't care about service

Horrible service, for the last 2 months I been having problems where I cannot receive calls, I'm am continuously given codes to punch in and the problem persists... I was then told they having problems with all numbers ported from MTN which was resolved for about 2 weeks. At this point there are many people telling me that when they dial my number it says "the number you dialled does not exist" yet I have voicemail on my number, certain people get through and certain don't, the number linked to out intercom cannot contact me, my wife which is also in the cell c network has a problem calling me, however if she calls from her work phone she gets through.... Yet cell c tells me they will escalate the issue, they then send me a message giving me a reference for the escalation, I then have my phone ring twice, a call from cell c , the call then cuts and I receive a message saying my line is active therefore the issue is resolved????????????????? I call back, told I was being put through to the technical Dept and the call was cut upon transferal. If I cannot get this sorted in the next 48 hours I am porting all 6 numbers I have with cell c to a different network...
