I received this call today stating that I have a faugulant tax case against me and to contact this number to stop an arrest warrent being put into affect. I called the number back and they answered US treasury dept. I stated to them "no this is not the IRS would never ever call me they would send a letter and that I am reporting this number to the attorney general's office, the FCC, and my local law enforcement agencies and to remove my number from their call list". The response was "OK" and hung up. I blocked the number.
