ISO son born 12/16/1984

I am searching for my son born in Marietta, GA on 12/16/1984. I have run into a roadblock with GARR and don't know what to do. GARR was unable to contact my son. They were able to contact his parents. The parents said they told him and he wanted to think about it. That was this past summer. I am having a hard time really believing that he was told. GARR said they would revisit it in the future but I am thinking they are referring to years and my heart is crying out now. Any suggestions? Any angel searchers? I paid for the full search and no one from GARR talked to my son. My heart is aching as we just passed his 24th birthday and I feel as if I am at a deadend without hope. All prayers welcome. If you can help please let me know. In Jesus, Lori
