If installation is this bad, I don't what to know about the service

Subcontractors didn't show up first time. Then drove off without finishing the job the second time. Also tried to charge me a fee though Optimum said there'd be none. Optimum doens't seem ever to get get that this reflects on them. They called me for four weeks straight to asking if I wanted to reschedule. No. I'm not paying for an over-priced service that I can get for free by asking my neighbors politely...not without an assurance that if I have an issue in the future, there's some hope of them satisfactorily address it. A different idiot calls me every weeknow, totally unaware that I wasted two Saturdays on them and nobody has even acknowledged it.
