FujiS,
Use your zip code in the Congress web site to find who your Congressman is and write to him/her for help. I wrote to Congressman John Culberson who represents the 7th District where I live and he has inquired on my behalf and gotten a response. Although my case is still not resolved, at least I have some information. I also wrote to Senator John Cornyn around the same time but his office has not gotten me anything, it has been over 3 months. The lesson is that you have a better chance with the Congressman. I hope this helps.
