I didn't need a letter. Just 12 months statements I printed myself from the app together with bank book both of which showed transfers. Also bank statements from the bank the transfers were made from.
good grief. You have to prove its money from a pension? I've never heard of that before. My office just wanted to see money out if my uk account t correlated to money in to my Thai account. It's possible that they will not require the transfers to show as international in my bank book. All questions I will have to ask when I get back.
Krungthai have been the best bank for me but I can not get Wise transfers to show as international for Visa purposes. That's why I opened a BB account. Anyway, I will not be trusting BB with more than a few baht once I have got things sorted.
exactly the same for me and it could affect my next Visa extension. As soon as I get back BB is over for me. And if, for any reason, you are unable to return to Thailand the money is gone!
My IO accepted bank statements I printed from the banking app. That might help you if yours did. In my opinion, bangkok bank will loose a lot of customers over the problems they are causing. I have simular issues to you.
There is nothing underhand about asking an agent to help you open a bank account, putting your money in it and getting help obtaining the non o at the same time.
