i got a call from this number and they left a voice mail made by an automated system that said that it is the IRS and if i don't call back they will take criminal charges out on me and that there will be an arrest warrant. I when to the IRS website and it said that the IRS will send a letter first and they will not say that they will be arrest warrant or any criminal charges and they do not ask for money over the phone. this is a scam i have already reported this number to the IRS website irs.gov
