Sending The Box For Phone Repair!

I got my phone box yesterday afternoon and inside was an instruction manual telling me what too do in order to send my broken phone in for repair and i did all i was told and brought the box to the nearest fed ex and sent it back with my phone inside. The instructions say i should get a receipt and be able to track my order but im unable to do so because when i go to the tracking link it still says my box is on its way even tho i've already sent it back earlier today!
