Question about refunds!

Hmm.. After nose surgery, the tip of my nose was protruding. I got a few steroid injections to correct the scarring. I thought it would get better, but the color has become dark, and it looks like one side of my nose is sticking out a little, so I want to get a refund. I'm from the U.S.... Of course, I had it done by a Korean doctor at a Korean hospital... I heard that if something goes wrong, you can get a refund by choosing Solomon in Korea?? But I'm curious. Maybe it's because I'm in the U.S., but they gave me a lot of documents to sign before the surgery. It was too long and bothersome, so I just read it briefly. The results after nose surgery may not be as desired. I think it was the content, but do they sign and have surgery for something like that in Korea?? If I signed something like this, wouldn’t I be able to get a refund?? ㅜ.ㅜ It was my second surgery, so I paid a lot of money for a reoperation, but I want to get a refund as well as psychological compensation... so I wouldn't have to go somewhere else and have a reoperation or not.
