Received a call that went to voicemail.  An automated voice said this was a final attempt to notify me of a federal matter and I needed to call back to get a case number and speak to someone.

I have received a total of three calls in the last 2 days. All three calls left voicemails. The best part was at the end of the last two voicemails an automated voice said, "If you don't return the call, then the only thing I can do is, wish you good luck."
