Pathetic service from MTN

I have app**** online for an upgrade more than a week ago. Since then I have received no communication from MTN. I have tried to call them and all I know it that the upgrade was approved. The approval was done on the 29th of July. Since then no finalization took place.

Here are all the reference numbers where I tried to make contact...

MTN Refno: *** – No response *** – No response *** – Escalated – No response *** – No response *** – No response *** – Escalated – No response *** Opened @ 3:18 *** Closed @ 3:19
