Who called from 6472436001

Duct cleaner yahoo's.  This is one of many phone numbers being used by this company / group of people

Alarm system company...calling on a Sunday afternoon.  Thanks again CRTC for enforcing your useless Do Not Call List.

call from this number saying they are Chubb Security.  Hung up when asked if I could call back. Obviously not Chubb Security

Picked up the phone but no one there.

Some kind of alarm system. I just told them to take my number off their list.
