that is the only way you can get a 12 month statement from BKK. It is impossible to get an exact 12 month statement as it takes a week to get. So theoretically, you have not given them a 12 month statement. You can get it down to a couple of days short my way.
Immigration were the ones to call for a 12 month when a photocopied passbook and letter sufficed before.
