Who called from 8018506188

I havr recived acall from this number saying i have been.aproved for a loan up to ten thousand dollars

Total scam.   Ignore it.

See:  http://www.consumer.ftc.gov/articles/0078-advance-fee-loans

caller claims to be collecting a debt owed to IRS... SCAM.. just trying to get your personal information. When I told him that the IRS hadn't informed us of this matter, he hung up... also uses the name John Wilson...

This phone number is a joke.  They left a threatening VM and an american name with a very THICK accent and sounding like they are in a moving locomotive.  I googled the law firm name and then, called them.  SCAM SCAM SCAM

He is calling to claiming to be third party collector he is a scam artists also threaten to send a letter to my employer and take me to court
