Looking for any ideas as to why this 3 unit intercom isn’t working properly. Units cannot hear anyone or speak and the buzzer gives a humming noise when the button is pressed. Not sure if it’s an amplifier problem?? Using a Pacific Electronics amplifier AF-1000.

Hello - I have a ton of pine trees on my property. Over the past few years I have had nearly all of them removed to ensure they don't fall on the service drop line. I am down to my final batch of trees. When I got a quote to have them removed, the tree company told me they could not take the job until the power company trimmed the trees away from the main power line because it would be too dangerous otherwise. Right away, I submitted a "tree trimming" request to my power company. They came out and left a note that said while the trees do need trimmed, it is not urgent and they would prioritize my house in 2021 during regularly scheduled maintenance. Over the past few weeks we have had bad storms and one of the trees in question began falling into the line. Some branches are in the power line at the road and the supply line is wrapped around one of the branches. I contacted the power company again but they refuse to do anything. I told them that a private company wont touch it due to proximity to the main line and asked "what should i do then just let it fall?" They responded "I dont make the rules, we aren't cutting this and left." You can see from the pictures, this tree is right next to the main pole with branches into the line. If the power company had trimmed it when I asked over the summer I could have had it removed by a private company. But now since it has fallen I don't think the private company will do it since it's so close to the line. Should the power company be responsible for this? Should I file a complaint with the state's utility commission?
