I received several calls for somebody else from this number.  
When I called back, I found out that it was a collection agency called Global Credit & Collection.  
I found there website ( http://www.globalcollection.net/Consumers.aspx ) and contacted their main number.
They told me that they would remove my phone number from their files, and they did.
