Seriously bad service

The rewards department called me and arranged upgrades for multiple numbers. One of the upgrades were never processed even though I requested it. Then the other upgrade was done, but the phone was never delivered. I have been trying for 3 weeks now to get the upgrade reversed so that I can do the upgrade in store and get the phone I was promised. When I call the call centre, I get transfered multiple times and no one can get the job done. I am incredibly disappointed and will not recommend Vodacom to anyone.
