It's a scam. They go by different names, however they sound similar to each other & are probably the same person. (Or perhaps two.) The IRS does not call on Saturdays, normally leaves an 800# for return call, & does not God Bless anybody. They leave different call-back phone numbers. In six days, we've received 5 calls. Now we let all calls go to answering machine, so we can have a record. Somebody Anybody: how do you stop this stuff?
Like you we got the same Carl Cooper call this morning, 02/21/2014, identifying himself as from the IRS and wishing us good luck if we did not call back. When call back was attempted on a land line phone the number was picked up and then immediately hung up. When called back on a cell phone line it was answered with background sound of many other speakers and the person on the line would not identify themselves in response to inquiry as to whom I was speaking. The person who took the call merely kept asking for my name but would not identify himself nor his badge number nor his affiliation.
What bothers me is that they got my home phone number which is unlisted. I confirmed like some of you did that the call came from the Washington DC area.
