Mike,
I too have suffered from easyJet cancellations but I'm surprised that they have left it this late. I got the impression that they took a view about 2 months ahead and then dumped the flight (quite legally though totally inconveniently) if the load was not looking good.
If/when you go for your refund, make sure that you follow the link from the cancellation email. Unless things have changed, any other approach eg into the website will involve you in such frustration that you will probably smash up your computer.
Hope this helps. Perhaps someone nearer to easyJet can comment?
