Are you someone in Seoul who is concerned about international schools for foreigners?

Hello! It's been about a year since I came to Korea, and these days I'm worried about the issue of international schools in Seoul as a foreigner. I work in Seongnam, and recently I was surprised to see news articles about international schools. They seem to have a lot of problems because they are not properly accredited. There was even an embezzlement case at Seoul International School... I'm really worried that students are not being protected in these situations. Does anyone here have a similar experience? Are you worried about your children's education due to issues related to international schools? If you have been harmed by these unaccredited schools, I'm curious how you dealt with it. I tried to contact the education office, but the process is complex and it doesn't seem to be easily resolved just because I'm a foreigner. Is there anyone who can offer advice? I would be really grateful ㅠㅠ I would be really grateful if you could share your experiences!
