Don't post this here, nothing will happen 

Hello Jun,

Thank you for your message. We want to make sure we give you the right support for your situation. 

Please contact our support teams directly by sending us a message via your Inbox tab of the extranet (under Inbox > Booking.com messages. If there is no "compose new message" directly there then click on See Contact Options > select a relevant topic eg. Account > select a relevant subtopic eg. Other > then click see all contact options > Message > write your message)  or tap More on the Pulse app. 

We’ll do our best to get back to you within 24 hours, but sometimes it might take us a little longer. You can help us answer your question more quickly by choosing the right topic and subtopic for your message.

You can also call us. To find a dedicated phone number to call, log in to the extranet, click on Inbox and then click on Booking.com messages. 

Booking.com has also published a list of publicly available support numbers per country on the page I have linked here, so if for any reason you can't access the extranet or don't have access to the Inbox tab, you will find a list of public support number numbers by following the above link to the Partner Hub.

All the Best,

Ivana
