Phone call from 202-780-6273 claiming to be IRS. Didn't answer call but listened to voice mail. Claiming I owed money and a suit was being filed to collect money owed and to call the Treasury or IRS at the above number immediately to settle debt owed. I have received phone calls like this in the past. Put their number on my block call list again. IRS will never call you on the phone. They only contact by mail.
