Received a call from this number on my cell phone purportedly from "IRS--Internal Revenue ServiceS" (If you are going to try a scam, at least get the department's name right!!) It was to inform me that "IRS is filing suit against you." Big time scam!! IRS will never call you unless you have called them first and are to be called back.
I just got this call too. When I got as far as to tell them the method of payment they demanded (I do owe and I've been working on paying my balance down so I was a bit freaked out) they simply told me a sherif would be on his way to arrest me. So freaky!!!
I just received a recorded call from this number stating that the IRS is filing a lawsuit against me too. I'm getting a refund, so I wasn't worried and knew this was a scam. Very annoying though...
