Argh! Almost had my OBC!!

I reunited (just by e-mail so far) with my bmother last year, and in January she suggested that I get a copy of my original birth certificate. The social worker at the agency in Georgia that reunited us said as long as it was OK with my bmother, she would go ahead and request it from vital records. My bmother sent her an e-mail saying it was OK with her, I sent one requesting it, and they sent off the request in early February. About 3 months later I hadn't heard anything, so I wrote to ask the social worker what was up. She said it sometimes takes longer than expected and just to be patient. I wrote again a few days ago because I still hadn't heard anything. She wrote back to say it was on hold and by the way, I would have to petition the court to get the OBC unsealed. I wrote back saying I was confused, because she told me she had everything she needed and had already ordered it. She then just said their relationship with vital records had changed since January, and I would have to petition the court. This is so frustrating!! It's not like it contains any information I don't already have. My bmother told me exactly what was on it. But I still want a copy, and so does my bmother (and my mom). I was told I could get it, and then I'm told I can't. Another really frustrating thing is that this social worker had been so helpful in the past, and now she not only didn't tell me anything had changed until I had asked twice over a 6-month period, but is being so vague I can't tell what's going on! Anyone have a similar experience or any insight or advice?
