They keep calling me! WTF?

Continuous nuisance calls from this company about a supposed "business matter".

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.

ya me 2

They phone me twice a day. They even woke me up in the morning. I'm sick and tired of these scammers. I don't answer it because it says its from united states and i'm located in canada.
