Ryanair says there is a typing error in your contract and the bond was for a longer period then you thought.
Get that in writing before they wise up!
Unless you've signed a new contract with typos corrected, you'll win any claim for compensation. Nice little (or big) leaving bonus!
Of course, the best trick in the first place is to get the milkman, or the dog, or the neighbours five year old to sign the bond. None of my bonds have ever had my signature on them.
