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.

It's global collections, they want your money, and mine

(905) 413-8731 phoned, and when answered, said " press 1 for english", for curiosity I did, then it said they would be right with me, to which I said "F" that and hung up. They have called multiple times, we leave the answering machine on, they hang up
