i would like to open a case of fraud and scams in Phuket Patong
I definitely remember reading a while ago that Phuket does have a branch office of the “Vice” department or some such thing. Sorry I can’t help you with more details but it might be a start to somehow contact a government website to try and track it down. Obviously, this will require someone with fluent Thai.
Doing a quick search for “Phuket anti-corruption office” produced some links that might get you going.
