Whoever calls from 4807682249 must not want to talk very bad, because they NEVER leave a voice mail and I always miss their call because I am working.  I can see that I have missed calls from that number, but because they don't extend the courtesy of leaving a message, I don't call the number back.  I guess if it were that important, they would practice courtesy and leave a message!

Received call from 480-768-2249, they didn't leave message.  I called back and they identified themselves as Theresa at Medical Resource Systems, A Debt Collector.
