Says they're from Bridgewater Group....asking for someone that is not at this location but I told them I did not know who they wanted but wouldn't tell them that.  Looked up Bridgewater Group actually website and they had posted on their site the following:
SCAM WARNING:  Parties claiming to be with Bridgewater Group have been making calls to collect alleged debts.  Bridgewater Group is not a collection agency and did not place these calls.  We have reported this matter to federal authorities and are investigating these parties.
