I got the run around in 2019 and just went to an agent and for 1000 baht they did all the work whilst I went to the coffee shop and relaxed. 2 days later I met them at the bank and just signed the papers. I can't remember what I needed but they will tell you.
that's good to know. I had to send more funds as the first lot didn't show on the statement that it came from overseas and all of it sent via Transferwise. Next time it's a visa extension so maybe slightly different.👍
