I still think there must be some misunderstanding. Could it be
(red text my edits)?
his schedule is this
1 8 hour classroom
1 DAYCONFINED + OPEN WATER
1 DAY OPEN WATER
Was your course a $99 special? I ask because when a course is very cheap (such as $99), several things typically happen:
1) Class sizes are generally very, very large in order to pay all the expenses on a practically non-existent profit margin.
2) Classroom sessions cannot provide much individualized attention or explanation or discussion since the instructor's attention is divided amongst many students.
3) In-water skills-development time is very brief in order to make the course shorter in duration (so another group can be scheduled to begin sooner).
4) Dives that are done on a rotating basis (some students in the water, some waiting their turn to enter the water so that ratios are not exceeded) have to be very short in order to finish at a reasonable hour in the day, so there's not a lot of practice time.
5) Courses are often scheduled so that one day is dedicated to classroom work, half a day is dedicated to confined water training followed by one or two open water dives in the second half of the day, and a second day is given to three additional open water dives to complete the work.
If in fact your course was a "$99 special" and was conducted something like the way I described, you merely got what you paid for. While it's never okay for an instructor to violate training standards (such as leaving students unattended in the water), it is very naive to expect excellence when you don't pay for it, even when the instructor meets all standards.
No matter how much you paid, I doubt you'll get a refund of any sort. Some mistakes are costly.
