A 4kw project and a 6 kw project ready for install...

A 4kw project and a 6 kw project ready for installation in February 2016.
A first electrical contractor cancelled just before installing any panels, causing a 3 month delay in both installations. Trying to cancel the contract to have it done by a local company (also much cheaper) was followed by threads of law suite to the ring of $10k.
4 kw completed and functional in June before they got paid (June).
Now 6 months after 6kw panel installation completed, still no production (Nov 2016)!!
nobody concerned but me...
