Travelstart.com took my money and no booking confirmation

I made a travel booking online 3 days ago. The money has gone off my card and yet I have not received my booking confirmation. I have been emailing and calling the travelstart call centre for days now and no one can assist me. I've been sent from pillar to post. Was told that I should make another booking and the funds would be transferred. Now I am receiving emails from them asking me which account number the funds where paid to.

How am I to know that if it was an online card purchase. My money is gone, no one to help me and getting no solution from travelstart.com.

I regret booking with this company and I need my money back urgently
