I don't answer calls I don't recongize, I was left a message and said I owe alot of money to the IRS and I would be arrested if I didn't call them back.I knew it was a sham because I just finished my taxes and always file yearly, and no I don't owe the IRS, LOL. I will be reporting this to the IRS on monday! It's a shame theses scams can't be traced or stopped!!!!
This is a scam, you should absolutely call them back and waste as much of their time as you can, but at the end tell them that the trace was successful and authorities have been dispatched then hang up.
