They never refund the reservation fee.

I went to about 6 places, paid a reservation deposit for the best one, took a blood test, and scheduled a surgery date. However, I
 saw a lot of bad side effects reviews about that hospital (not just one or two), so I requested a cancellation 3 days before the surgery date and asked if the reservation fee could be refunded. They said they couldn't do it haha. They said they couldn't refund the full amount, and the reason was because it was the hospital's policy and I
 had already agreed to
 
the non-refundable policy. Haha. I also made an appointment for surgery and suddenly canceled it, so I was sorry. I did, but I never made a reservation for a small amount because the entire amount was non-refundable ㅠㅠ
 But the staff said they would connect me to the manager and made me wait, and even though I called several times, they said no. ㅇㅇ had already agreed to non-refundability ㅠㅠ I'm only using it ㅠㅠ
 
Before I saw the reviews on the side effects. It was a good hospital, but they only cost a few hundred thousand won and didn't
 even perform the surgery, but they were trying to rip me off lol. It felt so bad that they were looking at the patient for money, so I really lost my sense of humanity ㅠㅠ I further promised myself that I would never have surgery here. When I
 
contacted Sobowon, they said I could get a 90% refund before 3 days. They say that signing the hospital refund contract has no legal effect, so if they don't refund you, I'm planning to file a claim for damage relief.
 
Everyone
 pays the reservation deposit carefully. Listen and help me ㅠㅠㅠ
