Unrestricted APN - open ports

I requested unrestricted APNs on eight numbers for the use in modems. The reason for this is that the ports should be open for data communication.

On Saturday I phoned AGAIN to confirm the unrestricted APN. I have now spent four days, including my weekend with another engineer fault chasing problems, only to eventually find out (after I used an open MTN card) that the ports on my cards are NOT open.

Our operation is three days behind schedule! There were unplanned costs and I am the one that has to account for this, not Vodacom.

Since the poor souls that answer the help desk phones have no idea about opening ports it does not even help me to phone. Could somebody from the TECHNICAL desk please contact me.

Much appreciated
