I received several phone calls from this number. When I call it back I can never get through. It hangs up on me. They call me in the morning each time. Sometimes they even wake me up.
It is a recorded message. It says they are the IRS Investigation Team. It seems they are sending the police to capture the people if we don't call back in 24 hours. I contacted IRS and they do not call taxpayers. Be careful and contact IRS before releasing personal information
