You will not be flying with EUJEt or anyone similar on that ticket - they are gone bust and you will be way down the line of unsecured creditors. You will not get your money back.
Book somewhere else quickly or if you paid via your credit card stop it or block it as soon as possible. Ring your credit card company right now. Ask for a chargeback immediately. They will not want to do a chargeback so scream and roar. Then roar some more to ther supervisor and insist that you institute a chargeback on EUJet. With a bit of luck the moeny may not have transferred to EUJet from your card if you booked in last 72 hours.
Edit I have removed the last two lines of your post. It is potentially libellous. Please use some sense. These pages are for you to use that way not to get PPRuNe fighting libel. Yellow card!
: I also deleted your third paragraph for much the same reason.
