Says that they are the IRS and yeah they are suing me too. Left a number for me to call back 703-831-3385. I tried to call back but the phone rang three times then went to a busy signal.
I had a phone call yesterday morning from the above number and I didn't answer. I was surprised when I listened to the message that it was a live person and she was telling me how we owe money to the IRS. For the fun of it, a few minutes ago I called this number back and a recording came on and said "this number has been disconnected due to suspected fraudulent activity." So that's good.
