Vodacom Upgrades are useless

Vodacom is honestly one of the most useless companies around.

Trying to do a contract upgrade is virtually impossible. Ten days later and they have done absolutely nothing despite numerous queries and confirmations by sms I have still not received the device. I have now been advised that Vodacom cancelled the upgrade as the device was returned to them by the courier company due to the fact that Vodacom did not put a delivery address on the waybill. And of course Vodacom could not bother to communicate with me. Seems no one actually knows what they're doing. Each time I try and follow up I gwt a different story.
