Is it too bad manners to change into surgical clothes on the day of surgery and then cancel the surgery?

I had cheek surgery, but after seeing the side effects I had read the day before the surgery, I stayed up all night debating whether or not to
 do it. After thinking about it on the subway on the way
to the hospital, I thought about it some more and said I would get it next time. I canceled the surgery and left the hospital.
 
But when the counter staff left, they said goodbye. He didn't even say hello and the atmosphere was very cold..
 
More than anything, the manager who was so friendly said, "I'll think about it more and then let you know". He hasn't seen my KakaoTalk message for a week..
 
Am I blocked by any chance?

I don't know much, but did I break this unwritten rule that you should never do in the plastic surgery industry??

I also had square jaw surgery at this hospital 3 years ago. Isn't it a bit too much to block them by becoming a black consumer just because they canceled the surgery?

Or am I like the restaurant Jinsang who canceled the order after making a reservation for surgery and making all the preparations, but then canceled the order? (I still paid 200,000 won for the reservation fee)
 
I really don't know, but what kind of case is this?

1. The manager is unfriendly
 2. I
 need you
to give me an answer.
