The phone message said they were the IRS on my landline - "final message . . . ". The IRS does not have that particular phone #, have paid my taxes and there are no issues. Must be a scammer. I blocked the number.
Just received a call on my smartphone from this number. Unidentified caller so I didn't answer. They left a message saying they were calling from the IRS and that it was a "final" call. Blocked the number.
