In my tired state last night I accidentally booked a room at the Conrad Dubai last night. Apparently when I hit the back button it defaulted to the current date instead of the date I wanted (today). It was past the cancellation window so I couldn't do anything. I do not have any way to call the hotel so I sent an email off no more than 5 minutes after booking explaining what happened asking if they could move the reservation to today. I got no response so what's my next course of action? I've likely been marked as a no show by now. I will arrive into Dubai at the hotel around 10am and will try to explain it then. Who should I ask to talk to for the best chance of fixing it?

Edit: never mind I got an email bank late this morning that they fixed it for me so all is well.
