Yeah wow I would absolutely demand a full refund.
AOW is supposed to be a fun series of dives that introduce you to 5 different 'disciplines' of diving in a fun way - it should be easy enough for a new OW student to complete comfortably, and you absolutely should have had the refresher dive, as well as a kit setup dive before the course.
Drysuits take a bit of work. my own full drysuit course featured a bunch of reading about how drysuits function, a pool session where we practiced buoyancy, inflation, dumping, what to do with runaway inflation, how to recover from inversion, correct donning and doffing, how to ensure correct fit, and so on - then open water dives ONLY after getting comfortable.
Some time later My fiancee got a drysuit, and didn't take the course, but she did read through the materials I had from the course, and we then spent probably 10 quarry dives together working on her skills, starting off on platforms and fiddling with drills and weighting, then moving to deeper water - I can't believe that anyone would believe that handing a student a leaky drysuit and expecting them to kind of 'work it out themselves' as part of an advanced open water course is a good idea, and, in fact, as we have seen recently with the case of that poor girl who was in the news, this is how people die in drysuits.
Reporting instructors like this is certainly the most effective way to ensure it doesn't happen to anyone else.
