iphone 8 plus incl Apple Watch series 3 "Yes sir we have stock, you will receive it in 5-7 working days"

On 21 Nov 2017 I completed the online application for a NEW contract, the application was successful and I was told both the device and Apple watch is in stock and that I would receive my package in 5-7 working days. However 5-7 working has since long past and I have been calling the after sales department religiously to find out the whereabouts of my package is. Every time I get told "awaiting stock on Apple Watch." But no one can tell me why I was told that there is stock at the time of my successful application and processing? No one can tell me when new stock will arrive? No one can tell me if I will even get my package in the next batch of stock?

After-sales say they cannot check with the warehouse for stock, even though some of them have done for me, some say I must phone direct sales, they say I must phone Online sales. Online sales say that they have different stock allocation to all the other departments, where is my package coming from? Online stocks' allocation?

What I don’t understand is, how can there be absolutely no ETA from the supplier to Vodacom? How is it possible that no one in the company knows if and when stock arrives? Do people just sit outside the warehouse waiting for a truck of stock to mysteriously rock up?

Details of Contract: uChoose Flexi 350 @ R919 pm Apple iPhone 8 Plus 64 GB (Space Grey) + Apple Watch Series 3 42mm (Space Grey)

Can any anyone please give me a estimate of when my package will arrive? is it 2 weeks? or 3 months? or 4 years?
