Telephonic upgrade done but no devices delivered and no I am being ignored by every avenue.

A consultant from MTN direct sales upgraded 2 of my contracts telephonically as well as my data line. Still they have not delivered my 2 phones and data device. I was not home and asked that they call after a certain date as they want me to receive it personally no one else can receive it. They have still not called again for delivery. I have called MTN customer services 4 times. I have spoken to an MTN direct call Centre person who said they would call for delivery. I also know an email was sent to the consultant who did my upgrade. I have also sent a message to MTN via Facebook but still no one is calling to deliver my Devices. What should I do? Report it as a case of theft of devices yet an upgrade was done on 5 November 2018?
