No stock no communication

I have app**** online for an upgrade. After no correspondence for three days, I phoned Vodacom and the operator said they have no stock of the phone and I have to phone back. Today when I phoned another operator said they do not have stock of the Gear that comes with the phone. After I insisted she provides feedback she estimated a waiting period of two to three weeks. If I had not phoned, how long will I have waited for them to tell me they do not have stock? And what is out of stock, the phone or the Gear?
