I have received several calls from this number.  They say they are a collection agency and are looking for us to pay a debt from 2010.  We have paid that debt back in 2010 and it was resolved.  When I try to call back the number, it says the phone is either disconnected, changed, or some other reason but I cannot reach them.  I called the creditor to whom I had owed the money and they said there is nothing in their system that says I owe any money.  I'm sure this is a scam.  I looked up the number in reverse phone numbers and it belongs to someone named Caila Conn in Buffalo New York.
