Not able to port forward

Ive been trying to port my number from autopage to mtn for more than 3 weeks now. Its been a constant battle, I first went to a branch and they said I i have to go to mtn and they'll just do it. So i went to mtn and we tried to port and it got declined, then I called them and they said i had been using the wrong account number in the application because i was with nashua. Then we tried again and It got declined again, then I called back and a really rude operator told me because the account is in my fathers name he has to sort it out, and put me on hold for 30 minutes. Then we called again and they gave me a new account number cause the first one they gave me was wrong, we tried it got declined, then i had to change it to a Postpaid subscriber and I still got declined. So all i want is for someone to call me and tell me EXACTLY what I must do to port my number. My contract with you guys is finished, and im still paying that same amount every month cause you guys wont let me leave, and that's unfair.
