Jakarta will be walk-in till the 21st. Going the online e-visa system from the 26th. Read their website. I suspect sticker visa in passport this week and pdf emailed visa next week.
This question is asked 100 times a month and the answer is the same. It's a matter of persistence each branch has its own policy and you're in an area where there's limited amounts of banks, you'll need a certificate of residence from immigration you'll need to dress nice, would be best to have a Thai person introduce you or just try and bribe the bank manager with 5,000 baht other than that go to Pattaya and pay that $5,000 to an agent.
nobody knows what will happen with extensions yet, and if you can't budget accordingly what are you doing living overseas? Expect to spend 200-300k in 6 months.
Who knows and who cares about DTV extensions. Border bounce will be the preferred expedient method.
Think about it, I don't think there is a snowballs chance in hell that immigration passport control officers at airports or land borders are gonna pull DTV holders aside sort out soft power applicants from remote and freelance and demand documentation similar to what was provided to the MFA during the consulate application.
