This has fraud written all over it....... They need an option under call type that let you choose Scam Artist.
They just called me and the number on the message was this number however, the message they left said to call 323-319-5920. The message was as follows (of course a recording).
"Action that has been issued by the US Treasury department regarding Tax Fraud against your name. Ignoring this would be an intentional attempt to avoid initial appearance before the magistrate judge or exempt jury for a federal criminal offense. So before this matter goes to federal claims court house or before you get arrested, kindly call us back on our number as soon as possible. The number to reach us at is 323-319-5920.. Let me repeat the number is 323-319-5920, Hope to hear from you soon before the charges are pressed against you. Thank you"
