I have contacted the actual Williamson & Brown and this is a scam beyond words. The information I have is this law firm no longer practices, and there info has been stolen for this scam. If you get another call from this number get all info possible and turn it over to the FBI so they can catch these people! DO NOT SEND THEM MONEY!

Received the same type of call today.  Said I needed to call an 800 # (800-651-9637) and referred to a claim number that is attached to my social security # and checking account # and I had 24 hours to call and verify this information.  Said they were from a Williamson & Brown, no other identification given.
Sorry I won't be calling back to verify any personal info, I don't know who these people are and why they have my personal ID.

I received a call today, 6/19/12, from this number. What seemed to be a recorded message instructed me to dial 1 for more info on documents they supposedly have on me referring to my social security number, checking account info and the name of what seemed to be a law firm was mentioned. I did not dial 1 for more info. Seems like a fraud call. I'm interested to know if others have received similar calls.
