Just go to Sukhumvit branches !!!! Bangkok bank asked me just passport validation certificate from the embassy and i opened the account on covid extension, not even visa. However any other branch that is out of that area will reject you. Also once you change your passport you will be able to do so only from the branch you oppened the account , so get one that works until late because mine is until 16:30 haha
seems like me host is not willing to waste its time to do it and want me to waste mine instead. I remember that before was possible to do it online through some app, is it still possible?
