They said they were the IRS suing me.

There are numerous telephone and email scams in which individuals claim to be employees of the Treasury Department. These scammers often state that they are from the “Department of Legal Affairs,” offer grant money in exchange for you wiring a small payment, or threaten to arrest you within a short period of time unless payment is made. Do not provide personal information or payment to these individuals.  Their actions are crimes under Titles 18 and 31 of the United States Code, and the Treasury Office of Inspector General is working to stop them.

If they claim to be from Treasury, report  it to OIGCounsel@oig.treas.gov with a description.  If it was a phone contact, include:
the exact date and time that you received the call(s)
the phone number of the caller
the geographic location and time zone where you received the call
a description of the communication.

If they claim to be from the Internal Revenue Service (IRS) or it is about taxes, report it to the Treasury Inspector General for Tax Administration at:

Received my 4th call from this number, with a message claiming to be the IRS.  Regular English voice, but with broken English message.  The Scam wants you to dial their number that it claims is the IRS.  I put a block on the number after the 4th call went unanswered by me, but they left a message.

I got the same call and at first I was freaking out! After some research and thanks to internet and also for you comments.

Received several calls from this number. Caller claiming to be the irs
