good luck then. it won't be a easy hunt for "botch job responsbile clinic" though. as you still can't find any answer in this thread.
suppose maybe 30% botch job case, two-third are from those big bad heavily promoted clinics & local clinics who reject foreigners, one-third are from the remaining good clinics. in that 10% out of all ps you have more than half PRC born Chinese who would rather post their reviews in chinese forums. so maybe 3% of remaining are english speaker & not every of them would post in this forum, some would go to google review but its sometimes flooded by fake reviews. (the stats is just a suggestion)
people also tends to complaint more than praise.
even if you finally get a responsible clinic review from here, would it be written by the clinic's own staff?
good luck
