MTN phone upgrade delivery

For the past week and a half I have been waiting for my upgrade phone to be delivered to me.

I've been in constant contact with the delivery service, trying to find out when my phone will be delivered, only to find out that they had the received the wrong contact number from MTN, so they couldn't get a hold of me. Then last week I'm told that the phone is being sent back to the warehouse, and I should contact MTN so that they could give them the right contact number (even though i gave them my number multiple times). When I did contact MTN, I'm bounced from operator to operator, only to eventually be told that i need to speak to the operator that called me and offered me the upgrade. I have emailed them, and asked another operator to get that person to call me back so that we can sort this out but have heard no response.

In all honesty this has been the worst experience I've ever had with regards to delivery. I've been with MTN for years, and this is not the kind of service i expect as a loyal customer.
