porting

I have been trying to port my number from mtn to telkom for two months now and mtn was failing to release me, which they did this morning. and I tried to port via and I have been receiving sms from telkom saying that theirs been technical complications about my porting process and I must expect a call from telkoconsultant and nobody is calling. When I call free number they are telling me to try again and when I try the same message is coming. What must I do?
