Left a voicemail:
"...Arrest warrant against your name under USS(N?M?). So before we could go ahead and start the legal actions on your name we want to...your retained attorney of record to give us a call back at 202-241-0233 I repeat the number 202-241-0223. Do not disregard this message. If we do not receive a call from you or your attorney your warrant will get activated. Thank you."
Hey, arrest warrants are issued, not activated and they are served in person, not by a robocall with no identifying information.
Blow me, scammer.
