Got a call from this number on Apr 02/09. I never answered it... just let it ring (live in Eastern Canada).

It's a collection agency called Global International.  
They have a website for consumers that are getting called:

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.

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.

Got this call from a Mr.beaver telling me to phone back this toll free number at 1-+1 866-993-1995 ext.8655. Apparently if i didn't phone this number back that "further action would be taken against me". Yeah right!

I received a message to call 1-+1 866-535-0623 ext 8701.  Firm and pressured voice stating he was Mr. Bizerro and that he and his colleagues had been trying to reach me for some time without success.  Time sensitive matter.  File # 3686771.
