Hotel check-in, no refund, no reminder.

If the hotel you booked didn't check in and you didn't receive any reminder, you can try to solve the problem by the following steps:

1. Negotiate with the hotel customer service and ask if you can get a refund.

2. If the hotel doesn't refund as agreed, or doesn't receive any reminder, you can call the consumer protection hotline 123 15 to make a complaint.

3. If the above steps can't solve the problem, you can contact the customer service of the reservation platform for help.

If you are booking a hotel through a third-party platform, you can try to contact the customer service of the platform for help. In addition, it is recommended that you read the relevant terms and policies carefully when booking a hotel to avoid unnecessary trouble.
