Only when you do a charge back with the credit card company and they have lost the money. Suddenly they are very keen to "rebook" the flights but of course they are more expensive. This company address is a bus stop in London, the real company owner is a well-know scammer in Pakistan. Sorry, with Brexit there will be more and more of these.

They have even not been issued. Prepare to be empty handed at airport and pay 5x the price for emergency booking. After that, Dream World Travel will claim that you cancelled the tickets yourself. This is how they make money. They have never sold a single ticket, see how similar all the positive reviews are? Fakes.

When you buy airline tickets, they will be issued within a few hours. You have been scammed by Dream World Travel.

Prepare to do a charge back with your credit card company as soon as possible and buy the tickets directly from the airline. In most cases you will be at airport with no tickets and Dream World Travel will keep claiming that you got the tickets until you have lost the will to pursue your money back. This is their modus operandi.

Inform your credit card company that you have not authorised this and according to internet resources this is a scam. If the credit card company has authorised it already, you can do a charge back. Keep declining as in the end you will win.
