Firefly good to take your money - but reluctant to give it back

I have made a booking with Firefly. I have paid my booking and then in the documents they've sent me I saw that one of the documents I needed was a credit card. I do not have a credit card. So I cancelled my booking in order to get a shuttle service. There story is that they can only refund me within 20 to 25 working days. I need the money paid back into my account within 5 working days. Otherwise I must cancel my holiday that I promised my girls. I just want my money before we go on holiday. This message must reach the top managers of this company.
