Robo IRS scam. Claimed I owed IRS money and if I did not call back I would be arrested for failing to pay my taxes. Message was garbled and distorted. Sad that they actually expect someone to call them back based on this message.
I LOVE calling these people. I always start by asking them if they've told their mother they're [***] yet. I then proceed to insult them some more with my best hockey language.
