That is fraud!! they just called me today, but little do they know I work with Gov.
IRS would not call anyone stating they owe money, is one, also if you receive a letter always call
the IRS directly get the phone number from google or a telephone book the yellow pages the middle is the blue government pages or get it from 311 and call to verify any letters received because some letters are also fraud. Be very careful cause Identity Theft is on the rise.
