I saw the earlier ( now deleted)reply - it all comes down to your own view of yourself/the world/unfairness of everything etc.,etc.
With most things, I simply adopt the view of getting on with it and trying not to get to hung up on things, if I can. Soooooooo, if this was me, whereas I might be a bit put out, I would wait for the correspondence to arrive, sign it and return it and then I would forget about it all entirely. Because the alternative is a Court application with the possibility that you might have costs awarded against you. How much worse would that be?
