same phone number but left message call me to have your number removed? why should I tell me who you are then I will call

Received this f***ing number call today. Let me press 1 to talk to a f***ing rep.

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.

I also got a call from 1-(905) 413-8676. It says "this is not a solicitor, press 1."
