Upgrading Online is going nowhere

On Sunday I logged onto app and selected new phone to upgrade. Email confirmation received. Monday morning I called Customer Care to advise the delivery address I typed in, was only partially displayed. I was informed nothing can happen as the Confirmation Department will call me. Well, its been three days of waiting and no one has contacted me and Customer Care line is not helpful as the call is locked. It would've been easier to just go to a Vodacom Store and upgrade, but now everything is on hold. Cancel the upgrade or call me to arrange delivery!
