I just received this call from 323-358-0906, it was an automated call to call back the number. When i called back some foreigner answered in 1 ring and said IRS Officer, How can i help you.. I hung up. Scary. I am glad to see this is a scam ..
New number, same scam, Its so common its been shown on the national news on TV.
The IRS does not call to warn you that they are suing you. The call is from a scammer trying to trick you into giving him your bank or credit card account number so he can spend all of your money. Hang up on him. Do not give him any information, not even your name.
