Caused $2000 worth of damage to my roof to install $3000 LEAKING gutter system. 3 young installers showed up without appointment, tore off old gutters in under 1 hour and smashed my aluminum roof and starter strips carelessly. New gutters with scratches, missing washers under screws, white caulk on black gutter joints on exterior etc etc. Unwilling to cover the damage they caused, owner gaslighting me, ghosting emails and breaking up communication chains, threatening to send to collections if I don't pay HIM for the damage they caused. Owner threatened to vandalize the house to "rip off" the gutter, Police were called. Complete disaster of a contractor, criminal like behaviour. What they should be doing is contacting their contractors insurance to cover my costs of the damage and correcting the remaining issues with the gutters like responsible people would.
