Legalese

Booking with Lastminute.com they insisted that I read reams of terms and conditions. One such page is quoted below and I suspect that many people wouldn't bother to read this gibberish. Trying as hard as I can I find it impenetrable. If it was translated into simpler English, I think it would read "When you give us your money, even if by some extraordinary effort you do manage to make a valid refund claim, we will hang onto £100". And what is a "compy"?
