Received automated message and I called back and they said I owe xyz. I advised i would visit my local IRS office in the morning and hung up. They tried to sound official by providing the ID and case number. I told them to feel free to mail me a letter if it's that serious.
Got call and they left a message stating the IRS is filing a lawsuit against me and they need more information and I should call back on their dept number.
I callled and asked to speak with their supervisor and the gentleman said, "hi this is the IRS and I am the supervisor." I told them I need to be taken off the call list, he said why, I said because it's a scam. He said ok that I need to expect the sheriffs at my front door and hung up.
