Contact Airbnb immediately, I am sorry I do not have a phone contact number for Malaysia but your best avenue of contact is via Twitter! If you don't have an account you can open one in seconds, it is free and then follow this procedure.
Step 1: Log into Twitter
Step 2: Search for @Airbnbhelp and choose "Follow" them
Step 3: Send a Direct Message (DM) explaining your issue and wait for their response. They may ask for information such as your listing but always provide it over DM so it is not public.
They will respond quickly, explain your situation and they will remove the guest.
This way there will be no penalty to you Joseph.
It is a strange world....while most of it is trying to get into your situation, you trying to get out of it!!!
Cheers.....Rob
