I received the same call! When I called back, the guy hung up in me when I started asking questions. I tried calling back, dead air then busy signal. My son said they used the voice changer. Amazing.
I received a call from this number today. They left a voicemail telling me it was the IRS and I should return the call before they take action. My taxes are in good shape so it was apparent immediately the call was bogus. As I read online, the IRS does not call but sends mail when there is any problem on your account, that way there is a paper record presumably.
I received the same automated message today. Since our taxes are in good order, this appears to be a scam to obtain personal information. We have never received a phone message from the IRS regarding our taxes.
