I don't know if is a scam but I've received a call from this number saying that is an officer from the IRS and that there is a case filed in my name for taxes that i did not paid and to call that number. the officer name was Walt Smith. I believe is a scam he had an Indian accent.  There is no record of this number in the irs. The number is located in Nassau County between Elmont Rd and Cerenzie Blvd in Ny.
