I ran a notice here on the bar about 7 weeks ago warning everyone of this type of operation. I was a prime rebuilding hurricane Andrews back in mid 90's. The real problem is the cable MSO allowing the prime contractors to screw over their sub in the manner you speak of. It won't get any better until all the snakes that call them self prime contractors are tossed out. Sorry to hear you were treated this way...good luck, I hope you get the opportunity of working with a true prime contractor that looks at subs as just an extension of their own crews.
