Trying to upgrade for the last 3 days - no service at all after upgrade was approved

I requested an upgrade on Monday, the upgrade was approve. Since Monday I have followed up in regards to the status of the upgrade. Firstly, they were phoning my data contract number hoping I will answer (I gave them the main contract number that they can use to contact me 3 times during different calls that I made to Vodacom). Today I have phoned for the 7th time to follow up only to be told that there is no stock of the laptop I ordered. I was told then to just wait till they have stock or go to a store to upgrade (Vodacom shops service level has gone down the drain). Or I can upgrade through the online department. I spend 3 hours on the phone holding on for the online upgrade department only to be rudely told that this is not their problem I need to speak to the ********** upgrade department again to sort it out. I still have not upgraded, two people have promised to phone me back, still no Vodacom. I apparently have some special advantage to being a RED advantage customer, still don't know what the advantage is.
