Phone number I received a suspicious call from today is (202) 957-5980.  He said he was calling from "The Department of Compensation".  When I asked him the name of the company, he said he did not work for a company.  When I asked him where he was calling from he said something unintelligible which I asked him to repeat several times without luck.  His heavy accent sounded Haitian or Cape Verdian.  
He said he was calling me because I recently had some kind of surgery (bladder mesh??), and I was a cadidate for compensation.  This was clearly a hoax and I told him so.
