Technicians arrived 6 hours early when no one was home. I called and asked the technicians what work they would be completing today and what they needed : they replied 3 times 1. Call someone else 2. Talk to someone else 3. Find someone else and left without doing the job. The technicians had entered private property and manipulated the gas valve and then left without doing anything because they had been asked to share the type of work they would be completing. Do yourself a favor and go to any one of the very competent and courteous technicians in Calgary. They're much more professional.
