Mnt worst service in the world... Actually no service

I am super frustrated. Did an upgrade online, the courier company that has to deliver my phone can't deliver to a 3rd party. No where during the upgrade did mtn state that they can't deliver to a 3rd party. I am on the road and am never available to wait for a courier to deliver a phone. I have been contacting mnt and no one can or want to help me. I asked their courier to cancel my upgrade they promised mtn will phone me.. Nothing so far. My account shows as upgraded but I still have no new phone.. Most pathetic service ever!!! I have been calling non stop and they either transfer me to non existing departments or tell me to call another number. I see this as ******** as they promised something they can't deliver. They are basically *****ing from me.
