unless u're going to give the date and time of the incident, the
cinema number/screen, the seat location etc. i dont think anyone
will believe you.
Also, it would be good if you could scan and post a copy of the
movie ticket for the incident in question.
Alternatively, you can write to the Straits Times forum, New Paper
forum, TODAY newspaper forum as well as directly to Cathay. Once
done, post both the mail you sent as well as the official
replies.
Thereafter - fine we'll believe you.
