Is it right to do it at the same hospital where I had the revision surgery?

3 years ago, I had double eyelid surgery for epicanthoplasty correction through incisions, and
 the double eyelids were even and the eye correction was the same as before.. But I had an acquaintance who had surgery on the same day at this hospital, and that friend also had double eyelid surgery, right? So I kept contacting them, but the plastic surgery clinic wasn't open, but now it's open again, and when I contacted them and said something, I told an acquaintance to come back. I also filed a complaint and said they would contact me again. Is it right for them to do the reoperation here? I think the first time I had it was a surrogate surgery haha... Now that I'm talking about it, the director said there was a seminar... Reoperation costs twice as much as the original double surgery... Oh, I'm worried.
