called and demaned to speak to someone i had never heard of. when i told them it was a wrong number, the woman called me a liar and said she was going to destroy my credit for hiding this person!!!!! they call constatnly and i keep telling them i never even heard of this guy they ask for!\

they call from 240-374-5474

I have been rudely harassed by their voicemails and would like to escalate to BBB...what are my options?

I got a call from these people.  Refused to identify themselves.  Looking for my daughter who hasn't lived here ever.  I refused to give them her current number.  And I won't tell them they're looking for her.

Who is this

The RUDEST Debt collection agency i've been contacted by. Save yourself the trouble of answering and just report them to the BBB. I've been in 2 full-blown screaming matches with 2 separate people calling from here.

First Revenue Assurance...   other numbers they have used include but are not limited to:
         
            800-203-1552
            800-452-6394
            303-595-4400
            800-226-2446
            877-422-8711
            240-374-5474

I just received a phone call from them. They are a collections agency.

They told me I owed XXX.XX amount and I told them that they were wrong and that it had already been paid. The guy yelled at me and told me he's reporting me to the credit reporting company and hung up on me.

...First Revenue Assurance...

(240) 374-4508 - called a family member - just said have important business matter - they already have my number - they have called it - no reason for them to be calling anyone else

Collection Agency. And they have the wrong number.

I got a call from this number around 8:30 a.m. this morning. I think I've seen it before. No clue who it is =(
