I'll admit that this is probably not the best way of dealing with this type of situation, but just because you have a contract doesn't mean that your client has to pay you. It only provides a legal advantage if you do take the complaint to court, which, depending on the budget for the project, might not be worth it.
Plus, if your client and you aren't in the same country, litigation gets even more complicated. I think this might be a valid way of gaining some of the power back as a freelancer. Maybe.
