MTN Upgrade

Good Morning

I got an call for an MTN upgrade on 08/05/2020 to do a upgrade, all went well and good until the 7-14 days passed for the courier to deliver my phone, upon calling MTN customer servers they told me that the person that handled the case open an upgrade for me but never completed it. sins then I tried to call them to close the upgrade so I can go into store and do an upgrade but the tell me I need to speak to a person on the new software in JHB to close the upgrade. And to make it even worse there is no number for that as you wait in the ques and hope you speak to someone in JHB. MTN store are also involve now to help me as they can also just send an email and hope for feedback.

PLEASE HELP.

My number *** Thanks
