Can Event Booking form be consider as a proper binding Contract

I order to attend a technical event, I had requested to book a seat for me. I also asked for payments details. But they were expecting GST number from me, who is an individual. Since time elapsed, and I was not able to provide payment, their early bird offer date also passed away. So I did not plan for the event. Now just before the event they are saying that the booking form that i filled up is suppose to be a "contract" and I am suppose to pay the money since they have booked a seat for me. I didn't consider that they have really booked a seat for me since they didn't took money from me. So is such kind of email conversation and booking form exchanged without any payment ---------------------------------------------------------------------------------------------------------------------- BELOW IS THE TERMS AND CONDITION MENTIONED IN BOOKING FORM TERMS & CONDITIONS: Payment: Full payment is required within 5 working days from receipt of invoice.
