Watgate .... sorry to hear your bad news, it was bad timing with COVID starting obviously.
The agency won't answer the phone
The office is just a closed gate
It's obvious he's done a runner
Getting a police report won't solve or do anything unless your looking to take the agency to court, which going down that road will just cost you thousands more and could take 12 months or even longer, to me that's pointless.
If it was me, I would find a Thai debt collector / fix it guy / enforcer .... offer him 20,000 if he can recover your 93k or as much as possible, pro-rata the offer. ( these guys are around, you just have to know who to ask )
sadly, that's about all you can do .... but I wouldn't hold to much hope on getting your money back.
hope you can get through this terrible ordeal.
