I cannot updgrade!

Me and my wife both have a contract with Autopage and want to upgrade. Autopage tells us that they do not have stock as they are being bought over by Vodacom and our contracts will be migrated to Vodacom. They also state that we must now process our upgrades with Vodacom. Which we cannot do because Vodacom refers us back to Autopage. At the end of the day I must hold Vodacom accountable as it is two Vodacom Contracts. Please can you phone me to process the upgrade or tell me what I must do.
