Who called from 6045581603

Telephone rang, displaying 604-558-1603 on call display. No reponse when call was answered. Attempted to call the number but only got a busy signal.

Repeat call from 604-558-1603 at same time every day for last 3 days. When answered, hear a beep then phone is dead.

Received a call for the past four days at approx. the same time of day, answered at all times (shows local number - 604.558.1603) slight pause before the phone clicks (hang up). Absolutely pi--ing me off!!

Its a furnace company trying to offer deals for furnace tune-up. Even when I asked them not to call again, they keep calling back.
