Delivery issue

I upgraded my router on 24 November, specifically stating my delivery address (work) and contact number. Vodacom gave my home address as delivery address and my router number to the courier. The courier has been trying to deliver to my home address and contact me on my router which cannot receive calls. I have contacted Vodacom three times to correct the delivery address and contact number (their error) and have been promised I'll receive the package on the next working day but it never happens. I have just called Vodacom and they have only the incorrect address and the consultant now says she cannot change it. This package has been on the road for nearly a week and it seems I will never receive it.
