Has anyone had a refund from Ryanair......??!?

Ryanair have recently cancelled a previously scheduled lunchtime flight from Stansted to Venice changing it to 0630 hours, obviously I was unhappy about the change of time but had little option but to accept as the holiday over there had been booked and paid for separately. I have now noticed that this earlier flight if booked today would be �120 cheaper than we paid months ago does anyone think/or has anyone ever had any a hope of gaining a refund or is this a non starter. So galling to have to leave home at 02.30 in the morning with a 6 year old instead of a reasonable time and to know that we've also "lost" �120 into the bargain..................... (Their phone lines are �1 a minute - I could get 2 hours of musak - I've tried getting in touch with them before!!)
