I guess not every place near Gangnam Station is good? I have photos,

I had nose surgery at the end of March, and I had it done at a fairly well-known place near Gangnam Station... Because they said blood had pooled, 2 days later I had to undergo another surgery to remove the pooled blood. Really, having sedation anesthesia again and getting back on the operating table was something I hated more than death .... But around mid-May, I ended up having surgery again, because my nose was crooked,,, they said it was something like moving the nasal strut. They talked as if it was nothing serious, saying it was not even surgery,, that is how they spoke,,, but sedation anesthesia... I heard sedation anesthesia is not good for people... To have that again... I really wanted to die, Still, I did not want to live worrying about the crookedness, so I did it again but... the result,, it has been about 2 months and it is the same.. Nothing has changed from before,,, I do not want to get revision surgery at this hospital again. I want to get a refund and have it done at another hospital. Would I be able to get a refund? Really, from late March until now, maybe because my constitution is different from others, the swelling and bruising have also lasted for a long time, so I have not been able to work or earn money, and the losses are not small at all, Everyone, please make sure to reply, Would a refund be possible? I am scared that if I bring up a refund for no reason, they might not even perform a revision for me. But I am also scared to have revision surgery at that hospital,,, Every day is nothing but sighs, Oh, and isn't pooled blood the doctor's responsibility? Everyone, I really ask for your replies,,,,
