What people need to understand is that Immigration don't want anything to do with the DTV because they don't issue them. They don't have the application info on their system so have no way of validating them. Hence they're basically refusing to do extensions and telling people to border bounce.
Anonymous participant 861 I seen that post too and he deleted it. Probably because too many people would have gone there on his recommendation.
I've had a Krungthai account since 2015. March this year I went to update my phone number and passport. I assume they saw my DTV stamp. Still working fine now.
