Pathetic service again!!!!

Vodacom upgrades department called me to initiate an upgrade. I agreed to the terms and conditions and was told my new device will be delivered within the next 1 or 2 business days. (This was on a Tuesday). More than a week later and I'm still without a device. When I queried this, I was told by RAM couriers that they can't find my address on a GPS. The address given to Vodacom and the one they have is not the same. I gave RAM the correct address on multiple occasions (4 times) but apparently they can't change the address, Vodacom needs to do that. Vodacom can cancel this upgrade! Pathetic service!
