Vodacom upgrades fail and seal from the public

I did and upgrade last week Monday via online, and was told they have stock on the Samsung Galaxy S5, and that I will get my phone the next day or two. After day 3 I phoned, and found out it was on back order, after I had to phone Vodacom again. I only got the phone Thursday. Ever since it came out the box it is faulty, and now I get told I must wait for 3 weeks for a new device? Why can't I just go and swap it out at a Vodashop? Now I'm gonna get billed at the end of April for my new device, after I wont even have it in my possession for the month. Is this not *****ing, as I'm paying for something that I don't have? I've never had any issues with Vodacom, and I've been with them for 10 years, and now this? When saying that I'm reporting the matter on Hello Peter, I was also told by Kugan that it will not help me at all, as it will only make matters worse! Great customer care, I must say! Well done Vodacom!
