S$379.95 was made for ad-hoc payment! Whats that!!!?? How am
i going to camp! How would an nsf survive the month!? anyone with
experience of this please notify me..and tell me whats the
outcome..thanks
Rot in camp and don't book out. You will survive like
this. 
Back to the topic, call up and check where your $$ went.
I suspect that you sign up for something.
