I heard from a person who heard from a very very very reliable source (I know this sounds weird) that Customs only releases 30-40% letters notifying your package has been seized and that they don't have too notify you.
Take that with a grain of salt, mind you, but why don't you e-mail your source?
This is why you should do:
1) Registered Mail so you have a tracking number
2) Be in contact with your soucre.
