MTN poor service

I received communication that i was due for an upgrade. I got a call from an MTN consultant that was trying to help with my upgrade, we tried doing the upgrade but then was told that i have an open order so she assisted with getting that closed so i could upgrade. tThis was on the 17 May 2023.

Numerous times after that date I have tried myself to upgrade, after I received an SMS that the order was closed. However, every time I get an error that there is an open order out on my number. After getting that I call 135 and Im told the query has been escalated and will be closed with 48-72 hours. Couple of days later i try again and i get the same error, call 135 and same story 48-72 hours for the query to be closed.

I'm just trying to upgrade to a sim only deal and cant believe that I have to go through so much trouble to give extend my contract which is mainly business for MTN. I cant believe it would take over a month to close an open order and allow me to upgrade, the service that i have received thus far is poor and does not show how mtn values their long time customers.

Can I get assistance in upgrading without being told that i have an open Order.
