This just another Ill-disguised scam to suck money out of the unwary and obtain personal data for identity theft. The number is spoofed, robo-called on a tie-line. Blocked.
I called the number and played along with them, supposedly I had miscalculations on my 2005-2010 returns.. Steve Lee (a foreigner) ID# IRM4507answered the call and told me what I owed the IRs and did I want to settle in court or out of court. When I said out of court he had to transfer me to another person who wanted to know if I had the money in cash or did I want to make payments. They were going to send someone to my door to collect what I could pay. That's when I told her they were scammers and to never call back.
I received over 20 calls from this number. At first they offered a loan to pay off my IRS Debt. Then the remaining calls were then stating there is a lawsuit against me. I tried calling the number back and it said the Google subscriber isn't available.
