Autologous rib reoperation, have you ever had a case like this?

Hello..
 It's been 3 weeks since I had a revision surgery at a two-letter hospital near Sinsa Station in Seoul.
 I paid a lot for the revision surgery (around 12 million won)
 . This hospital is famous for its expensive prices. When
 
I woke up after the surgery, there was a stitch in my philtrum;;
 It moved during the surgery and got a scratch and stitched up..
 
On top of that, the stitches on the columella part had burst on the day of the surgery, and
 I found them the next day when they were removing the cotton;
 so I went to have the cotton removed
 
and had them stitched up twice on the burst area. Also, the flesh flew away from the costal cartilage area while changing the tape.
 
Then, my stomach hurt all through Chuseok, so I visited the emergency room twice and
 I've been hospitalized since Chuseok.
 The diagnosis was diverticulitis and peritonitis...;;
 
The hospital just brushed it off, but
 the more I think about it,
 the more uncomfortable it feels, so
 I'm asking.
As you can see in the pictures, there's still a red line on my philtrum, and
 the part where the costal cartilage flesh fell off hasn't healed
 . I wonder if this is something that can just be overlooked, so I'm posting this to hear your opinions...ㅠㅠ

 Will it ever go away..? I apply German scar ointment every day, but..
 I'm so stressed out..
