I received the same call from "Mike Anderson" as well and hung up in his ugly face, because I know it was a scam. First off.........How can an indian dude with that strong of an accent have that name? SMDH. I'm up on my IRS ish and I know this was a scam.
Same story, the IRS will never call you they would rather waste stamps. Don't call these a-holes back as much as you'd like to tell them to take a flying leap at a rolling donut. This puts you in with another set of [***] heads that will call you back with a new BS story. I've bean dealing with these sscammers for 2+ years. Don't call them back!
