Complaint after paying 800,000 won for a perm at a university hair salon

(1)a note
(2)Chonbuk National University Hair Salon
(3)Hello, I’m the one who’s in the hair salon case I borrowed my brother’s phone and wrote Etta I got a perm called IV perm at a hair salon in college, and I got an IV perm
(4)I’m going to have IV perm setting perm hair cut like this
(5)When I first made a reservation at a hair salon with Naver reservation, I asked about the total price through Naver Talk Talk, but I will let you know when I visit because I can know the price by looking at my hairThat’s why I visited
(6)After visiting, I asked again about the price before the procedure, but he said he would let me know after the procedure
(7)I don’t know much about IV perm, and the lot is 6,000 won each I found out this much after I went to the hair salon, and I thought it was similar to the price of a regular perm and got a procedure, and I was charged about 800,000 won to pay after the procedure
(8)I was flustered and asked if this price was right, and he said you could pay and go, so I paid first, came out and settled the matter
(9)I asked again in NAVER tone What’s the price, what’s the price
(10)Then I said there were 70 lots, so when I calculated it, it didn’t match the price. When I asked again, he said there were 100 lots, and I felt a little bit curious about him reversing his words, so he kept taking pictures of his hair throughout the procedure. I asked him to show me the pictures of the procedure, but he said he couldn’t
(11)Is there anything that I’m thinking wrong in this situation
(12)After that, I acknowledged the mistake I made in notifying the price through Naver Talk and said I wanted an apology, and I wanted you to compensate for the damage to some extent, but I wrote that I had a receipt review of about 800,000 won because I was out of contact. It’s my first time experiencing this situation at every hour, so I’ve tried a solution
(13)I wanted to know so I wrote this
(14)Currently, a YouTuber claims that everything is my fault, saying that if you don’t contact and delete your post, you will make everything public on your blog and Instagram and create a difficult situation What should I do
(15)The salon has filed criminal charges of defamation threats and has been cleared of charges. During the criminal investigation, a lie detector investigation was conducted on whether the salon’s claims or my claims were true, and I received a truth response and was acquitted In addition, he said he would file a civil lawsuit through proof of contents after the criminal acquittal, so he replied that he would correct any damage to the proof of contents, and most of the blog posts were deleted, and only about 800,000 won was left
(16)I’ve deleted most of Eta’s posts, so please don’t guess what kind of hair salon it is, and I’m looking for someone to help me with this situation
