Thank you.  My blood pressure doesn't need to go up any more.

I got a unknown number incoming call and the robocaller left a message that I have a lawsuit against the IRS and requested to call back immediately to this number 405-648-4366.
I knew it was a scam and I called to bacon ways it just kept ringing and ringing - made it more obvious that it was a fake agency and a fraudulent scammer scheme.
I goggle the number and found a bunch of complain.

I received a call from this same phone number plus two others, #360-718-9951 and #312-380-0163 saying that the IRS has filed a lawsuit against me and I should call right away. I was nervous when I first heard it but then realized that it didn't sound quite right. I looked up the phone numbers and did a trace, all three of these phone numbers are a scam, please don't fall for it and warn as many of your friends as you can.

Classic grandparent scam. "I'm in jail, need bail, can only make one short call, don't sound natural because my mouth was injured..." I don't see that this number has been used for that scam before. Guess they're expanding.  My husband listened for a while and hung up, then a different voice called back from the same number saying he was a legal defender.  I said the man you called is incompetent, I'm his caretaker.  He hung up.
