FYI: I've been a long time Android user and can tell you that the process works different. And is actually not as bad as you think.
1) You call the hotline, they send you a link via mail 2) Clicking this link will place you in their shop with a promo-code 3) You buy the replacement phone 4) Once you've got the replacement you send in the broken one (or if you feel like it earlier) 5) Once they recieved the broken one, you get a refund on you purchase
Knowing this process so well is the reason I've bought me an iphone 7 now ;-)
