Go to the municpal authorities and check all the local ordinances in regard to noise levels, business affairs, neighborhoods, etc.
Hire a lawyer if you have too. I've been in sitautions like this in the past, that is why I now live as far away from other people as possible. No civility anymore and business intersests seem to supersede the interests of tax paying homeowners. Go to the county commision, the media, social media, whereever until you get this grievence redressed. You have EVERY RIGHT to be upset!
