I just received a call that I let go to voice mail.  The guy left a message that made it sound like we had contacted him with a mortgage refinance or debt consolidation.  He left a few numbers and stated that we have been making minimum payments - we don't have credit cards.  I called back the number he left and asked to be put on the do not call list the lady who answered took my number and said she took care of it while I was still on the phone.  (It was a one minute call.)
