It would make sence that this is Global Collection network, I owe them money and I see this 413 number on my phone all the time, I never answer since I muted calls from that number (good ole black berry)

I recieved a call from Mr. Beaver asking me to call 1-+1 866-993-1995 ext 8655 to avoid further action being taken against me. Left a message but no return call.

It's a collection agency called Global International.  
They have a website for consumers that are getting called:
http://www.globalcollection.net/Consumers.aspx

Left message on home phone to call or Mr. Beaver would have to take action.  Told to call 1-+1 866-993-1995 Ext 8655...won't be calling.

Found a message saying that Nick Hines needed a call back, that it was urgent I call back.  Number he left was 1-+1 866-535-0623 ext. 8723.  I called back and left a message that I had returned his call.  I won't be answering any others. I'm in Northern Ontario.

I have been getting calls from this number as well and when I have tried to call back I get a recorded message that says to stay on the line. Eventually they said to leave a message on their answering service. I have left 2 messages telling them that they have the wrong number . My call was from a Mr. Singh. At present he is supposed to call me back in the next 24hrs. Also they said that further action would be taken. The number I was to call was 1-+1 866-535-0623 ext. 6604
