DETERIORATING STATE OF MTN

I have been a customer of MTN for more than 10 years. So I have sufficient historical interaction on which to base my next statement. MTN IS GOING DOWNHILL FAST. Over the last 2 months I have found it almost impossible to upgrade a contract. After various dropped calls on ***, I went into an MTN store in Alberton City and was met with blank stares and disinterested responses from the staff and manager on duty. I decided to change my upgrade request to a number port request at that stage. This has resulted in numerous back and forth between MTN and the other service provider and after a month the number has not been ported. A week ago a got a call from an MTN agent offering me a upgrade. I conceded and decided to give MTN another chance. After 7 days of no feedback I call the contracts department and they inform me that the upgrade is still in a vetting stage??? MY upgrade via another service provider took 3 days in total including device delivery.

Could someone please assist me to get my number ported to my other service provider so that we can close the chapter on this horror story.
