Booking.com Won’t Change My Ticket Date

I’m having a tough time with booking.com right now. I’m stuck at the airport with a ticket to fly to UAE. I’ve been calling them since yesterday to cancel and change my ticket for the next day and they keep referring me to Emirates but I didn’t pay my money to the airline they took it. I called Emirates they managed to cancel it, now 5-10 booking.com consultants don’t know what to do they keep saying I must go to Emirates. I just spoke to a consultant now he said he will call me back and I’ve been waiting for 30min
