I haven't picked up a Letter Box in years, but from what I remember, I don't think one of these white Xbox boxes would of fit through that slot in the first place. If you did actually cram one in, please tell the UPS Driver or leave him a note on the box so he can try to get your box out. As far as tracking this package, I think Microsoft issues a work order number where you can track it on their website. You may want to call 1-800-PICKUPS and report what has happened so that we can get it on its way.
