Cancelled flight tickets

I booked a set of 2 return tickets on booking.com on 07/05/2025. The funds were debited from my account. On the email confirmation I was advised that an airline confirmation is pending. I sent a chat in the evening at around 20h00 pm, and the agent advised that there is a technical issue and my booking has not been confirmed as yet however it will be confirmed. The agent I spoke to was Kaushiki M. I then sent a chat again this morning after receiving an email that one of my bookings was cancelled, and spoke to Quan H who advised that I need to wait for 4 hours to get the confirmation. While I was chatting to Quan H,my second booking got cancelled, I told Quan H and he said I should wait because on his side it shows that it is pending and he disconnected the chat which is VERY RUDE! Both my bookings have been cancelled without my consultation or making contact with me and advising what is happening and providing me with a solution. How is it my fault that there was a technical issue on your side? Why am I being refunded when I clearly advised that I do not want a refund but I want my tickets? I contacted your call centre on the number *** and spoke to Taran who was unable to assist me and told me that a supervisor will get back to me after 24 hours. Taran also does not know the turn around time for a response for this email I am sending which is very disappointing for a customer service agent not to know ANYTHING!! I WANT MY TICKETS AND NOT A REFUND AND WILL BE TAKING THIS FURTHER SHOULD NO ONE GET BACK TO ME AND ASSIST ME!
