If you saw ads on jobstreet, try apply via their HR email as well.
They will definitely look into it rather than clicking not suitable /ignore your application at jobstreet.

As said above, the filter system in Jobstreet is a double edge sword. Good for HR/agent for ease of filtering candidates by *racist* and bad for foreigners.

Malaysian still ok la to get approved by MOM. Got special rate some more compare to other nationality.

Yes it will. why you want to cancel it anyway? better offer from other co?
