I've gotten a couple of calls from (403) 800-4479, they do not leave voice mail.  All I know it's an Alberta #.  Anyone know who they are?

This is a collection agency named ARC Accounts Recovery Corporation

They just called me, some lady asked me for info about one of my neighbors two doors down. She wanted to get in touch with them, apparently they moved away. She also asked if I had seen a for sale sign on their lawn.
