Left an automated message claiming something about legal matters. I called the number and an Indian or Pakistani man answered "Thank you for calling the FBI. Can I please have your name". Obviously a scam. I told him I was Tommy Tutone and that my number was 867-5309. He claimed to have my records and that I am guilty of tax evasion. I have the option of paying him or facing arrest . He pranked him a bit more before I got tired and just cursed him out. He cursed back and hung up.
Make no mistake, calls like these are scams. The FBI is not going to call you up, ask your name, and then claim that you need to pay them or face arrest.
