Why is it the property's dereliction of duty for the gas company to check the owner's home and not report it to the property?

It is the dereliction of duty of the property that the gas company fails to report to the owner's house for inspection, because the people from the gas company have already entered the owner's house, and the property does not know, which shows that the property staff at the door did not fulfill their control responsibilities and did not ask for instructions and report to the property that someone entered the community. This is the dereliction of duty of the property.
