They have visited TESDA in DAO Pagadian a month ago to inquire on the same but they were informed that such course is still to be scheduled. in this regard, we would like to inquire on the planned date or month at least when the said program will be available for enrollment.

    we have contacted the center a couple of times but to no avail (no one picks up).
