A fraud recovery company, claiming they were subcontracted from the FBI
When I asked how they had gotten my #,  they said from the databases  of the companies they had shut they had shut down.
Asked General information about  how much money I had lost , How much we make a year, gave me a pin# of which I made up & said someone would be calling me back in a few days & I had to give that pin# again.
During the call it seemed legit, after i hung up.... I became paranoid that it was a type of scam.
