Why was my Thai visa application rejected after providing the requested bank statement?

Got rejected today from hanoi

I was rejected in Hanoi.

I work as a video content creator.

I applied on the evening of May 28, and about 3 working days later, I received a document supplementation request. They only asked for one thing: a 3-month bank statement.

I then submitted a 4-month bank certificate showing a balance of 700,000 baht:

* 31 May: 21,500.00 USD

* 31 April: 21,300.00 USD

* 31 March: 21,400.00 USD

* 31 February: 21,600.00 USD

What I don’t understand is this:

If my other documents were insufficient or inappropriate, I could accept a straightforward rejection without a request for additional documents.

But in this case, they only requested one specific document.

I submitted exactly what they asked for, yet I was still rejected without any reason given.

I don’t understand it at all, and everything feels completely unclear and opaque. Like this
