You already asked the same question on boards.ie and received an answer (if you'd check back).
The op cancelled them himself for reasons not elaborated on. As was explained on boards.ie fare rules differ so greatly depending on the fare type the only way to know if you are entitled to a refund is to contact your airline/agent.
Depending on the reason for cancelations you may have some recourse for compensation via your travel insurance (if you have any).
