Confirmation Booking Turned Down by www.asiatravel.com

I recently found a very good deal from a hotel in Langkawi, and decided to book a room through www.asiatravel.com. Since my reservation was successfully and I received a confirmation mail and slip, I went ahead with a purchase of flight ticket. But later on, asiatravel.com sent me another e-mail saying my booking was turned down...

I don't know what is wrong with them... How could they cancel my booking after sending me a confirmation mail and slip... Well, people out there be careful. At least luckily, I have not paid a single cent to this company.
