Damage claim denial

I submitted a damaged claim October 10th and did not receive phone calls or updates on the matter. I provided picture proof of the damage they created by trenching in my backyard. They severed sprinkler system electrical cords. This was not found until I needed to blow out my sprinkler system before winter came, and they were no longer getting signal to operate. I had to pay a professional to come back out, find the problem with the sprinklers, fix it, then be able to blow out the lines so they would not become damaged in the winter months. I escaped the matter with Xfinity, and they denied any compensation. Before I write the the attorney general and get the county involved, I want to know if there are other options.
