I got an email today saying that I'm going to be refunded for the cancelled flight and they won't be entering into any further correspondence - similar to your response mulking.
Details of claiming from Ryanair are here

What I am entitled to under EU Regulation 261
If your flight is cancelled, for whatever reason, the EU261 Regulation provides that you are entitled to choose between either of the following:
(a) Full Refund – The airline will provide a full refund on your unused airfare. (If you chose to make alternative transport arrangements i.e. car hire, trains, ferries etc. these are not covered under EU261 and therefore such claims should be directed to your travel insurance company as the airline will not provide reimbursement for alternative travel expenses), or
(b) *re-routing, on the next available flight to your final destination, or
(c) re-routing, on a future flight, to your final destination at a later date at your convenience.
*If, you select option (b) - the EU261 Regulation requires an airline to provide:
(i) meals and refreshments in reasonable relation to the waiting time;
(ii) two telephone calls, telex or fax messages or e-mails;
(iii) reasonable hotel accommodation in cases where a stay of one or more nights becomes necessary;
(iv) reasonable transport between the airport and place of accommodation (hotel or other).
I seem to have claimed under option a and so therefore Ryanair are saying that I am only going to get my cancelled airfare from them.
Next stop travel insurance.
