It's best not to do callbacks on numbers you do not recognize.
1) the number could be spoofed by a scammer and could be someone's residential number
2) you need to check the area code to make sure it isn't going to a foreign country like Jamaica (876)
that will cost you extra - a whole lot extra
3) if it is a scammer's real number they will record the fact that you returned the call and let other scammers
know it is a working number with an overly curious person who calls back.
Finally, some scammer left a message.
The reason of this call is that the IRS is filing a lawsuit against you. To get more information about this case file, please call immediately..."
Got a message on my answering machine from this number today stating that the IRS is putting a claim against us. I called back. A guy with a foreign accent answered. He was asking for my wife. I said I was her husband. The guy kept saying he couldn't hear me on the phone and was getting mad. I kept repeating myself and I was getting mad. Then he asked why I'm raising my voice. I said I repeated who I was several times and you said you couldn't hear me. Thats why I raised my voice. Few seconds later he hangs up on me. Tried calling back, but keep getting the busy signal. Must be a scam!
