This is my experience of dealing with easyJet. I had over 15 bookings cancelled most of which I was happy to move to other dates as I personally think they are quite generous in allowing (if the flight was cancelled) to change your booking to any destination and any date with no additional cost at all (not even fare difference).

3 flights I asked for refund:
1) online refund button was still available so clicked that and got my money back within 3 days
2) no online refund button, made my way through the labyrinth of links to find the refund form, submitted, received "do bot bother us" email. 10 days ago I went into the booking again (which should still be available, not through manage my account but through manage my booking - without login in) and voila refund button was there again, clicked onto it, money in the account within two days ago.
3) called their call center, managed to get through quite quickly (well 35 minutes) and the agent arranged refund which was in my account in about 10 days.

So if you asked for the refund via the form and still waiting for your money, try step 2, worked for me. Good luck.
