What if the hotel scans the code and forgets to refund in advance?

Contact the hotel for confirmation. After contacting the hotel, you can provide bank account information or payment account information for the hotel to refund. If the hotel is unwilling to refund, it can contact the payment platform or bank to provide payment vouchers and related materials, so that the payment platform or bank can refund. The specific refund process varies according to different payment channels and hotel regulations. Need to confirm the refund rules and procedures first, and operate in the prescribed way.
