Ya, so?  What did they say?

This is a tool used by Coface Collections.  You can not call this number back, it just goes to a strange busy signal. They call from this number to see if the number they have for YOU is real.  If you answer, then they ask a few "innocent questions" then they set their dogs on you.

I did not get the correct responses to my questions - so I hung up on them!!!
They avoided my questions .

The guy was rude never answered my question so i hung up on them... The guy called me back and threaten to tell my boss i was rude to him... after I asked him what I could do to help him because he was asking for the credit manager and I am not the credit manager I am only AR.  

We dont deal with Collections agency to get our money and figured he as just someone who wanted to charge us to get our money from clients.
