This caller uses an automated message saying that the you owe taxes and threatens to send the police if you do not call back to arrange payment. When I called and informed the caller that I had reported his number to the treasury department, he became vulgar and abusive.

Same thing happened to me. This caller uses an automated message saying that the you owe taxes but I called them back on my work number. Told them I was going to report them because the IRS doesn't call you. They will send you a letter in the mail.

They call me yesterday and I have been call them back every hour  since then it's great fun make sure you do *67 so they can't block your call if we all do this  it will drive them crazy

Got a message from this number today. Hard to understand the very broken English, but something about taxes and IRS and I was in trouble. Called them back and left my own message that they are busted and their stupid tactics have been exposed all over the internet. Drive them crazy right back, I like it.

Same experience with me they became vulgar and abusive when I asked more about their claim. I'm calling them back and told them that I would like to make a payment so that I don't go to jail and they hung up. It sounds like a make-shift call center in India.
