Vodacom
No stock for 3 weeks

I opened a new contract with vodacom and moved a number from 8 TA to vodacom, I have now been waiting 3 weeks for the handset, I have been to the Vodashop twice now and all they tell me is the ware house has no stock. For 3 weeks now, surely Vodaworld should have the stock available, when i asked if i could get the hand set any where else, i was told no i have to wait for it to come to the specific branch, I am thinking it was maybe a mistake to open yet another contract with a service provider that doesn't have stock.
