Krungthai Bank

To whom it may concern: I am a foreigner working in Thailand for more than 10 years now, I opened my khrungthai account more than 3 years ago because of my tax refund. I always have problem with your bank because my mobile banking (khrungthai next) updates and I couldnt access or register again without going back to the bank again. I called the customer's service already and they advised me to go to a khrungthai branch to fix my krungthai next. I went to the bank at central plaza suratthani at around 15:00 28/3/2025 but they're would NOT let me in, they said they were closed but the sign said opening hours is from 10:30- 19:30. 2nd time, my app has a problem again and I can't access it. I went back to the central plaza suratthani khrungthai branch again, they asked me for a certificate of phone number ownership from truemove so I went out of the bank and got it, I have to queue up again, then the teller asked me again for work permit. I am not a new customer and I have to travel back and forth from home just to get my documents. I do not see why they have to ask me different document everytime. Why not list all the necessary documents so I can just bring them all at the same time, why send me back home again everytime and ask for another document. It's a waste of time and resources. Other foreigners are also complaining about being asked for tax numbers from back from their countries even though they have been regular customers and they just have a problem with the app. I don't think this is professional. I believe this is negligence of duty and lack of work ethics. Please advice me on how do I proceed with this complaint. My problem with the app is not resolved yet as of the moment I am writing this email. I have to go back to the bank again tomorrow and see whatever 'new' documents they want from me to further delay the resolution of my khrungthai next problem. Sincerely, Edelmiro Domingo Jr.
