You are absolutely correct (604)683-4321 is an outgoing number for Eaton's Commercial & Residential Services Ltd. When you call the number back it says it is out of service as it is an outgoing number only.
Call (604) 683-4328 and ask to be removed from their calling list.
I too got a call to message was left. Initially the number showing on call display started with a V with a bunch of numbers.......looked like no one I know!
