Customer service complaint

This business suffers from a complete lack of common courtesy. I work from home and they've been installing solar in the building I live in. The work has involved a lot of drilling and a great deal of shouting from their employees.

Our building manager usually does a great job of keeping us informed about maintenance or any building related issue that might cause a disturbance. Dorman Projects have complicated his job by essentially showing up whenever they want, giving residents no opportunity to perhaps work somewhere else because of the noise. They may come on Wednesday. They may not. They may come on the following Monday, or they may not.

When they do come it's always an unpleasant surprise. Their employees use a heavy drill that's harsh on the ears to the point of physical pain. They also shout in the ceiling right above flats, or right outside front doors.

I approached their employees about the noise and they were rude. They refused to connect me with their supervisor, and conducted themselves in a way that suggested they have more right to be in the building than I do. Apologies, but I pay to be here, whereas they are paid to be here.

I emailed my grievances directly to the company, and I phoned them as well. I don't believe I asked for much. I respected that they have a job to do, and I simply asked that they send our building manager one day's notice for when their employees will be here.

They listened and told me they have no control over what happens on site.

I cannot speak to the quality of their work but their customer service is severely lacking.
