Can you send them a formal letter explaining you're loosing business because of their lack production?
And with loss of business due to their incompetence in scheduling, lack of production on a signed contract, and lack of "good-faith" effort to complete said contract work on good weather production days within a reasonable amount of time, you'll be forced to send assessed damages of business lost, to them in a "net10" billing. And be forced to seek another competent contractor that is willing to completed contract work on time?
