This number called my cell phone and left a somewhat threatening message. Said he was Eric Stephens and do not disregard this call and they would expect me or my lawyer to return the call. I was a sucker and called it back, and got the message it's not a valid number. So now I'm sure I've fallen for the trap and will see an increase in spam calls. *sigh*
I would advise NOT to return this call!

Just got the same call from "Eric Stephens".  Do not call this person back.  Thick accent, recorded message, and threatening words do NOT equal the IRS!  If there was truly a problem with your taxes, you will hear through official channels.  Disregard this call and block the number.

Just had this call on my cell phone.  Very obviously a fake call if you listen to the threatening tone.

Added to an existing contact on my iPhone called "Spam Call"!  ;-)

"Spam Call" is blocked in my Contacts list.  Goodbye Eric!

I just got a call from this number and it really freaked me out, the whole "I can only wish you good luck if you do not call back" so irritating

Amy. Today, 4/16/2015 I received exactly, word for word, the same message from Eric Stevens. Thick accent and all. The implied threats were also there.  I refuse to answer or call this number because it might allow him to latch onto me. I know they do not know my name....otherwise they would have addressed me. It stinks because no one likes to be threatened this way.  I wish him BAD LUCK forever.
