Yes i had my account frozen i had emailed head office about the situation and received a email back stating branch manager can unfreeze yourself account so i rang the manager who is in khon kaen and i am in buriram and argued the fact as to the reply i got back and 10 minutes later my account was opened you need to hassle then in a polite way and kerp at them
Just spoke with the ma of bangkok bank in khon kaen where my account is frozen she told me future bank accounts for a retirement visa will require your retirement information at your retiring age 67 in Australia don't know if this is right but wouldn't surprise me
