I had the same problem , I did manage temporarily limit increase to 100,000 for 24 hours . Managed to do it same day . Now I plan ahead with multiple transfers on different days. I still have BKK bank where I transfer larger amounts sending them to K bank after as I’m not confident with BKK bank any more
well I also did the right thing and my account was frozen until I took the same documents I opened the account with only 6 months ago , BTW still got 1M baht in the account
