Keep fighting them..Put that post of yours on every Filipino and tourist forum you can find..Send it to every Newspaper in Cebu ..There are lots of them..Just use Google to find them. Also email Cebu pacific..If they dont answer then bombard them with more emails until they do...Do the same on the P.I Gov forum about the way you were all treated by the Immigration officer. They expect that you will simply go away..DONT.
Be a sharp thorn in their side at least till they offer you some really nice freebies and a grovelling apology letter.
Im sure there are others here with better ideas how to embarrass these imbeciles ..
