The man said he saw I had surgery in the past. I told him to remove my number from his calling list. He said no, he wasn't going to do that. I'm said yes, you are. He said no again. I told him if he didn't remove my number I would contact authorities. He kept talking so I hung up.

From the IRS.gov website: IRS-Impersonation Telephone Scam An aggressive and sophisticated phone scam targeting taxpayers, including recent immigrants, has been making the rounds throughout the country. Callers claim to be employees of the IRS, but are not. These con artists can sound convincing when they call. They use fake names and bogus IRS identification badge numbers. They may know a lot about their targets, and they usually alter the caller ID to make it look like the IRS is calling. Victims are told they owe money to the IRS and it must be paid promptly through a pre-loaded debit card or wire transfer. If the victim refuses to cooperate, they are then threatened with arrest, deportation or suspension of a business or driver’s license. In many cases, the caller becomes hostile and insulting. Or, victims may be told they have a refund due to try to trick them into sharing private information. If the phone isn't answered, the scammers often leave an “urgent” callback request. Note that the IRS will never: 1) call to demand immediate payment, nor will the agency call about taxes owed without first having mailed you a bill; 2) demand that you pay taxes without giving you the opportunity to question or appeal the amount they say you owe; 3) require you to use a specific payment method for your taxes, such as a prepaid debit card; 4) ask for credit or debit card numbers over the phone; or 5) threaten to bring in local police or other law-enforcement groups to have you arrested for not paying.

Just received a call from a guy who had a foreign accent. He got mad at me when I asked him to repeat. He said he was with the US Government and wanted to give me a $9,000 grant. I told him that he sounded like a con artist. He got mad and used the "F" word many times. I didn't give him any information.

Called to say I have a $7,000 grant waiting from the government. I only had to phone the accountant at 509-207-4032. Did not call as I knew it was a scam. The US Government does all its contacting via USPS.
