I just received the same call, I answered, a prerecorded message said something about an undeliverable package and that I had 2 choices, press "1" to be connected with someone or to call the same number to make arrangements. I waited a few seconds and the call ended.
I did not answer the call because I did not recognize the number. They left a message saying this is going to be there very last attempt to deliver IRS documents to me.
Another IRS scam. Same tactic as the "pending civil lawsuit against you" calls that I also get multiple times a week. Why isn't there a "scam" option in the Call Type menu?
Left a message This is our very last attempt to deliver IRS documents to you. I also keeping getting a 703 area code number calling me saying something about last attempt to deliver some kind of documents. The recorded voice is the same from both numbers.
