[Breast Reduction] Sagging breast reduction surgery

I had surgery at Zenith Hospital last September, but the sizes on both sides were different, the mammary glands were also different sizes on both sides, and the sutures were a mess. One thing that is unfair. Because I reduced one breast so much, the nipple became sunken. The hospital said it would come out over time, so I kept buying nipple compresses and trying them, but they didn't come out. So I went to the hospital and met with a doctor. He said he would check to see if Sam's breast sutures weren't working well, but the counselor said I had to pay 150 for the surgery. It doesn't make sense~ It's because the nipple went in and didn't come out because the surgery was wrong, but they said. They say I didn't do anything wrong, but if I want to do it legally, they tell me to do it. But, it's the largest plastic surgery hospital in Ulsan, so that's why I go there. I'm going to get the service later, but if I do it this way, will I have the surgery in a local area? and also. I asked them to let me meet with the doctor, but they said no. How could something like this happen?! The breasts are different sizes! One nipple went in! Even the sutures were a mess! They said they would not take responsibility and told me to pay for reoperation!
