Why was my soft power visa application outright rejected with no explanation?

Applied for soft power dtv in Jakata, Indonesia. Pending approval for 7 working days and no single request for additional documents. And got outright rejected on 8th working day. No questions and no reasons.

I used an agency that is well known. The agent said my documents are strong and i am a good candidate. But i only submitted 1 month seasoning of 500k before applying because i saw in this group that most people only seasoned 500k for just one month and got their dtv approved. The average balance in six months is about 300k.

I also had a language school visa before. No idea what was the issue, my past visa or the bank statement. It is awful that there is no reasoning. Don’t remind me they don’t give reasons. I know. It’s just disgusting.

Edited: applied for Muay Thai soft power (6-month course) . I’m a Myanmar Nationality. I do have regular income from my own business in Myanmar for which i submitted the scans of original business licenses and notarized versions.
