On Tuesday July 9 (4 days ago). I dropped off my RMA nexus 4 at a ups drop box, with the shipping label Google sent me printed on it. It's Saturday and there's still no tracking information for the package on the site. Should I be worried? I live in Vancouver, BC so I would assume that the box is emptied out quite a bit. I really hope it's not lost because then I would be charged $400. Should I for a claim? Start looking for it?
