I was contacted by XXXX XXXX XXXX XXXX fromIntegral Recoveries Inc. It claims to be a collection agency representing the Colorado IRS department and states that I owe state property taxes from 2009. They have contacted me by phone twice in the last 6 months. They can not provide any details other than the amount owed. I 've never received a letter of notice from the IRS. My only communication has been through them.
