Yes. My congressman was able to get my VA disability restored within about three days after the VA told me it would take six months. The problem with the AF Retirement was cleared up within about a week with no intervention from the congressman. Unfortunately, there's still some paperwork floating around saying I'm dead, so every once in awhile something strange will happen and my insurance got cancelled and my mortgage company needed proof that I was still kicking.
The next time they say you are dead, go down to your local police station and ask to have yourself fingerprinted. Then have them write you a letter saying you are who you say you are and that on this date you are alive and well.
All PD's have people who are notary's. Get it notarized and then make half a dozen copies for the companies who think you are dead.
I'm trying to think of the common title for the person in a PD who assists the community with things like this but I can't.
