A call from "Chrysler Financial"

We got a call from these people too.  What are they trying to do??

This number is the third number I have reported for this phone call.  The caller ID shows that the call is coming from 800-685-8300.  The caller states to call him back at 267-308-7281, and the call shows up as 267-308-7200 on my received list of phone calls.  3 different numbers for one person?  They are up to something.

I also have been getting calls from different numbers for this group. I tell them the people they ask for are not at this number but they insist in still calling. what can we do to stop them?
