Trying to port to MTN

After 4 times of declining our port I spoke to 7 different consultants and each time there is another problem. We started the process on Friday 27th. After 4 declines I contacted Autopage myself. This was a disaster go and listen to the recordings. Finally yesterday I got a reference no 95662. This did not help ever time the port is declined. I have gone to MTN and phoned Autopage from my cell phone and checked that everything is done according to them. It always comes back declined. I have requested 3 times that a manager or someone from the porting department phone me but still after 17 calls and more than 4 hours on call center calls the port is declined again. Really is this service?????? Could you please assist as this is a corporate account and my Manager is having my head.
