They called this morning.  No message left.  I saw nothing online when I Googled, and it appeared to be a cell phone.  I called the number and they answered Transworld Systems.  I told them someone called me from there, but they looked up my number and found nothing.  Said they must've misdialed.  Second call just 30 minutes ago, which I missed.  Again I called them.  Asked what they did.  "Personal Business."  I asked if it was sales, and the lady just repeated her line.  I said it was the 2nd call I received.  She checked a couple files and found the number nowhere.  I asked where she was out of and she said New York.  So I pointed out that she was spoofing a local line to make it appear she was near me.  No response to that.  I told her I'd block that number so I wouldn't get any more calls.  Googling Transworld Systems shows it's a collection agency.
