mail fraud - what would you do?

I work for the postal service and there is no way a mail carrier can leave a package on a doorstep of it's insured and with delivery confirmation. The carrier has to file out a PS Form 3849 (small colored peach slip), which is a delivery notice slip releasing the package from the carrier. It HAS to have a signature, or that carrier isn't doing there job right. He's probably keeping your package for himself. There is also a standing delivery notice form PS Form 3801 or he can leave a Form 3849, saying you have a package that needs a signature and will be attempted again or you could pick it up at the post office.

Give the Postmaster hell, because I get reamed all the time if I don't fill out the proper forms!
