I'd say if it's dry now and you got good customer service, suck up your disappointment and go diving. It can happen to any suit from any company.
If it starts springing more leaks in a short period of time that could be an indication of poor workmanship. That can be an individual suit problem (sloppy tech, over dry glue, inattention to detail, etc), or a company issue.
My one caveat is if the repair looks like a job by a drunk gorilla having a bad day, then you could have a problem worth fighting over. Otherwise it's probably not worth the hassle.
If you are looking for permission or a reason to fight about it, far be it from me to dissuade you.
