This tidbit excerpted from the original post is why a formal complaint is highly warranted, regardless of the actual security of the letter. The clerk was in error (somehow) and assertive about being correct, then was rude. That level of misconduct by any clerk deserves complaint and at a level above the office in question so it cannot be swept under the rug as easily.

I had the pink slip in hand and the clerk was saying the day before it had been signed by someone. I was speechless, how could this person get the letter without the pink slip? I wasn't even raising hell when the clerk told me to leave his line as I was going back and forth asking how it could be possible for someone else to sign for a letter when they were neither the addressee (it was a business name) nor did they hold the pink slip. ...
This is the first domino in the event sequence and is where the problem really is. I don't see any "federal case" here. When my mail goes missing, I ask hard questions and expect honest, no-nonsense answers.
