How do I report a Telus truck driver?

I had an unfriendly encounter today with a Telus truck driver as a result of asking him to move his truck as he was blocking the approach to a back alleyway. You couldn’t see the approach and with oncoming traffic, inbound vehicles had to maneuver around the truck. After knocking on the truck to ask the driver if he could move to the parking lot merely 5 metres away, he got out of the truck saying aggressively approaching me saying that “we could go around and that ‘he has a business to run’”. I have a picture of the plate and would like to report this behaviour.
