Called the local PO again and spoke to the same manager. He told me that the form 3811 was not in the notified certified file but would look in another file. Nothing.
Around 315pm, I got the mail and the Form 3811 arrived, round stamped Nov 1, 1995. So weird. Also, it was signed by my 8 yr old stepdaughter, and right next to it it had the ex’s signature.
