Call from this number, supposedly from the IRS telling me to call 202-386-0453 to get details about why the IRS is suing me.  THIS IS A SCAM!!!!  The IRS does not call you on the phone, they send REGISTERED LETTERS in the mail to notify you of any problem.  DO NOT answer this call or call them back and definitely DO NOT five them ANY personal information.  THIS IS A KNOWN SCAM!!!
