Received a call from 360-450-0699 while I was driving and only got a call back number. Called a few time and no answer so I blocked it. After reading this thread I will not be answering that number, even though I have it blocked. I have dealt with the IRS before and they always send letters on why they are contacting you.
Received a call from an Asian Indian stating he was with the IRS Audit Dept. Very Rude! Said the IRS has a law suite for past taxes I fraudulently neglected to disclose details to the IRS from 2008 - 2013. That was the first clue, he was an idiot and a spam call. He insisted I either pay the $7K plus taxes owed TODAY or settle in court. When I told him I would need to borrow the money from my dad (who passed away 10 years ago), he insisted on a time I could process the payment. Somehow he know I was recording the conversation, the phone call went dead.
I received a call from number 360-450-0699 as well. It does in fact throw you back for a bit, until you finally can recover and give a proper reply. When I laugh after stating why would the IRS wait this long and use the method of calling on a cell phone the scammer said to me 'Why are you laughing?'. Holy cow.
