Sucks to lose a pack. Most sources have a resend policy as long as you have coustoms letter.
If it was from within states i dont know what to say but never admitt. maybe they will test it then watch you or come visit you once they know what it is.
I would 100% always say i dont know what you talking about,,dont let them break you. YOU DONT KNOW SHIT, nothing about nothing, some bad joke someones playing on a good guy. Keep home clean for a bit because they have nothing but time to sit and watch you. ((not saying they will)) Just be safe as you can be.
And remember nothing about nothing, a fucken bad joke, maybe you banged some chick and her boyfriends getting you back, who know but you dont know nutting.
