Stolen: Brooklyn Big Link!

Man it's becoming ridiculous!
I'm still being asked to prove that I'm the legal owner.
I've provided photos of it...lots of photos...outside my own house...even the photo sent to me by Brooklyn Machine Works in 2006 labelled 'Scott's Brooklyn Big Link number 8'....I've listed every single component, along with any modifications...which is easy seeing as I built it...all the distinguishing features...and to top it all off...a written confirmation from the company themselves stating that they made the bike and sold it to me....and I'm still being asked "Have you got anything more 'official' ?"
They're even asking me for bank statements from 11 years ago because they feel everything I've already provided is not enough 'proof' it's mine!
Now despite all of that I'm still being asked questions like "can you confirm the frame number again?".....
"YES...it's number EIGHT!!! One digit!!!"

Utterly ridiculous!
