General HVAC & Electrical

Gasline and heaters installed in 2015. Got 3 Warning Tags from recent Enbridge visit in late July 2020. 2 warning tags related to non-compliance of pipeline installed and improper support/requires bonding. The company was notified on the non-compliance. I have stated that the non-compliance work has to be fixed on or before mid Sep 2020 as we need heat for the greenhouse before temperature is too low. I and my son have followed up with multiple emails and phone calls in the past 2 months. The owner promised to come and fix the problem but either no show without notification or no definite schedule is provided up to now. We have requested multiple times but the company never call us back. I don't see that he company really want to fix the mess. We have written records for the communication with this company.
Also, during the first year after installation, the heaters were having problem and called the owner and message him to call back but got no reply at all. Afterwards I have asked him why and got no answer at all.
