The package is lost. It cannot be recovered, it contains nothing of interest and you need to remember that for your own safety. It sounds like the guy is fishing. They're spread pretty thin. Sign that and you're obviously worth a little more time. Throw it away because you have no clue what it's talking about, and you'll never hear from anyone again probably. Unfortunately... I doubt they'll just wipe it away from history that easily. So you best assume they'll be watching more closely.C'mon. It's junk mail. Don't you agree...? ;)
