Sorry to hear about the issue, i've had multiple anodizing nightmares in the past (precision, gruntbull, etc) so it really frustrates me to hear about anotech. For right now just regroup and take an inventory of exactly what you are missing.
If they don't come back with any good news I would try to talk with someone high up in Anotech. Time will not be on your side since it been a really long time since they probably saw the parts. Be cool, calm, and collective and make sure to document everything you can.
If you still don't like the answer I would drive down, or see if someone from AO can help.
Good luck
