Thanks all.
My contract is with the agency.
Looks like I acted too hastily when the agent told me to go ahead and opt out, assuring me there's no problem and that most people do it. Of course no one expected this would happen.
I was intending to work a few days during the notice period but I don't see what difference it makes, unless it looks better for me if this does get to court.
Looks I have to read up on opting out for my next contract.

You only lose a month's money, and is it worth being ignored for all those other contracts for years over?
