I would only blow them off (as the PP suggested above) if you can collect your final pay first.
And if paid by check, make sure it clears first.
You have endured a lot here OP.
But none of it was in vain.
You learned a hard lesson & I know from now on, you will not let anyone treat you like this again. Ever.
At least now you are equipped w/some better tools for your next job.
