I was there only a month ago, getting a new book. Everything fine. Have used QR scan four times in the last week and three transfers. No problem at all!
That's very strange as there appears to be no red flags on your account. I also use the monthly transfer method, but I've had no problems with BB since this banking issue started. Will they accept a scanned copy of your passport? Your branch will have a copy of your passport data page anyway, so it's only a case of matching one with the other.
I didn't get four months with Santander - that was instant. However, a phone call fixed it. I've had no issues with Bangkok Bank, it might be those who use agents that are falling foul of the new rules. I've never used agents so it appears I'm "above suspicion"
The banks will no longer support fraudulent actions. There's nothing wrong with that. Why should a bank put its licence and reputation on the line to support cheap foreigners. Makes no sense
