Booking a hotel on the flying pig shows that it is irrevocable, but I accidentally deleted the order. Will the hotel I booked be refunded?

No, go to the front desk of the hotel and say that you booked the room online. The staff will ask your name and phone number, and you don't need to look at your order on your mobile phone. But you must arrive before the specified time. The hotel booked online has the latest check-in time. After that, I will think that you don't check in and don't refund your money.
