A guy called me and said I owed $500 in tax returns. and threatened to get an arrest warrant, When I didn't give bank account information. Hanged up and they left a voice mail saying that they were the Criminal Investigators Department and that if I didn't call back they were going to issue a warrent for my arrest. WHen I called back a lady said thatshe was from the Criminal Investigation department, and asked for my name, gave a nickname, and then she proceded to hand up.THIS IS A SCAM, IRS NEVER CALLS YOU THEY ALWAYS SEND YOU LETTERS BY MAIL TELLING YOU EXACTLY WHO THEY ARE WHAT THEYRE CHARGING YOU FOR, THE REASON FOR THE CHARGES AND OTHER INFORMATION SO YOU KNOW IT"S THEM. DO NOT PANICK OR FRET WHEN THESE SCAMMERS CALL YOU. Always look up the number online. If these comments didn't exist, or the IRS website, I could have fallen for this scam.
