Vodacom upgrade ordeal!!!

I am receiving terrible service from Vodacom regarding an upgrde! I booked the upgrade on 17 Aug. Two weeks of calling after sales, upgrades and various other departments still no Phone delivered. They kept telling me that the parcel would arrive tomorrow. Also note that I was the one calling and enquiring. Vodacom never initiated contact with me, Vodacom never followed through on what they promised. 3 Sep I was told that the parcel went missing at RAM couriers. I was told that the upgrade needed to be cancelled which would take 24 hours. After the 24hrs Vodacom would contact me in order to reapply for the same upgrade. No call was received from Vodacom! Today 7 Sep I called Vodacom again only to be told that the issue needs to investigated and will take 7 days before the parcel can be replaced? 21 days after my initial contact for and upgrade and still no phone, no upgrade and no end in sight to this ordeal.
