Why are you si upset? You should be po'd at the interruption but if you get emotional about these types of calls, that's what the pond scum scammers want. Laugh at them and hang up! Never EVER donate, spend, buy, or give any info to ANYONE over the phone if you didn't originate the call! There, isn't that simple?
Ditto on reports above: owe $2000, arrest warrant already issued, wire $ when bank opens... Tried to get agent name and phone number authenticity verification from the local IRS office, but they haven't called back. The IRS gives good advice at https://www.irs.gov/uac/IRS-Urges-Public-to-Stay-Alert-for-Scam-Phone-Calls
Thanks for info on here - I looked it up before even calling back the number. Some of us are cynical enough to smell a rat, but sadly some people will be fear-triggered into obeying the suggestion, and may get ripped off. I wish Anonymous or some badass group would smoke these people out and hang them by a piano wire in the town square
