MTN corporate no feedback

Did an upgrade and call center agent was polite however process took in excess of 45 minutes. That was on the 3rd of January. Delivery of the device would take approximately 5 working days. After 5 working days I receive a call saying that there was a system error and the request did not go through but it has been escalated. When asked what I could expect from said escalation the agent advised that she did not know and would advise. No feedback received. ref:PT ********** 9 After waiting the entire day for feedback I called and was then advised that it would be better to go into a store and do the update. ref:PR ********** 8
