Is the surgery reservation fee refundable?

I went for a cheek and double chin liposuction consultation, but
 the consultation director pushed me to make a reservation, so I set the surgery date for a month away and paid a deposit of 100,000 won.
 Only now did I come across a site called Seongyesa.
 I was the fool who tried
 to entrust my face to someone after only getting advice from the head of the counseling department
 .....ㅠ..ㅠ I feel bad about not being able to meet a doctor and I want to compare different hospitals, but the most important thing is the good reviews of that hospital. After reading this article, I wanted to cancel my reservation.
 It's been 4 days since I received the deposit, so it's possible to get a refund, right?
