Random individual pretending to be IRS is claiming that you are under investigation.  Ignore this, it is a total scam!

Impersonating a member of the IRS, stating there is a federal case open on my property - I called him back (he said his name was John Miller), and asked him if he knew what he was doing was illegal - he told me he didn't have any other options to earn money - I reported this number to the FCC - hopefully someone out there is making an effort to stop people who continue to do this, I unfortunately have elderly grandparents that could be confused and taken advantage of by someone like this

All -- This is a HOAX. The IRS NEVER calls, nor texts, nor emails people. They send letters or come to your door. Disregard this parasitic A-hole....

[***] scammers they took 12000$

Did they now?
How did they take 12000$ from you?
