Ryanair Ash Cloud Refund

I am sorry if i am exhausting this issue but has anyone had any problem recieving a refund for the Ash cloud cancelled flights. I am still waiting on a refund for rebboking a flight when my flight was cancelled. Ryanair charged me for change of flight, web check in fees, handling charges etc to the value of €135.00. They asked me to send reciepts which the only receipt is my old itinirery from origional flight and the rebooked flight itiniery and a copy of payment on my credit card. I feel that they are hoping i will give up and not persue this claim and being ryanair they do not make it easy to correspond. Any advice would be greatly appreciated.

Perhaps they thought you had other expenses (meals, accommodation etc) which you wished to claim for.
I simply filled up the on-line refund application form and the exact amount that I had paid them was refunded to my card, no hassle
