hi sis, what name yung agency nung friend mo? Maybe I can look it up if its authentic.
also, 600sgd if that will be the processing fee and all.. is quite low.. Some agencies will charge for around 100k Pesos ($3k SGD), I know some people na ganun yung binayaran when they applied through an agency.. some even paid equal their salary pa.. which is sometimes can be $7k up! (for EP - P1, etc)
