Very very poor service delivery.

I did an upgrade with mtn direct approximately 10 days ago and the upgrade was processed by a Mbolokazi. The sim in question reflects the new price plan and changes yet the company mtn or DSV THEIR carrier hasn't delivered my handset to date. I have made numerous calls and emails to mtn with no luck and even visited one of their stores to rectify the issue and still no action has been taken. I am so frustrated and concerned that maybe my handset was ****** by one of the employees along the line. I have heard nothing and no joy what so ever with this network's service.
