<prompt> Human: Before we send them money we dont really have, I want to know if this is real. I googled the number and nothing came up. If it matters, the number was 8552685577. The person said they were from Offices of Baum and Demozi or something like that, it was hard to hear, and they had a file number. They are saying if we dont pay 200 dollars, which was approximately the original debt which has become 400 dollars with interest, they will sue us immediately. They will not take payments and say we have to pay today.  <response>: All of that sounds like red flags to me. Go to the second link from the AutoModerator and start dealing with them that way. Everything in writing, make them prove they own the debt, etc.
