Unprofessional ballet cl?

Over a month ago I started this ballet cl. I've only gone twice though. It's been years since and I just wanted to sharpen up on ballet for figure skating, as I read online it would help. But when I went there they didn't stretch and warm up, they went right in to the splits which I know could hurt a person. They weren't precise (there were two instructors). When I asked how my feet and arms should be placed, they told me I was doing it perfectly. Even though my friend was watching through the window who is a professional ballerina, she told me later it was all wrong. My dad is paying big $$ for this and I hate to see this. I'm not looking to become a pro but I just want to brush up on posture and gracefulness. They would start talking about the most random stuff. Should I still go? How should I go about finding a new studio? What would you do? I could possibly get real hurt because they didn't stretch or warm up in any way. I'm 17 and refuse to go to a little kids ballet cl like I did when I was 13.
