Yes, you answered your own issue, not handing them a printed DTV. If you have studied Thai or even in english, I wonder why you didn’t point them to your previous DTV stamp 🤔
also did you combine extra information and a cover letter in one pdf? I assume you upload it at the very last section where it asks for the medical letter, is that correct?
Thanks for your info. Can you elaborate on what additional documents? Are you saying the medical centre wasn’t accepted at first? Did the Dr put all their details and clinic stamp on the first document?
Interesting about the bank statement being a different address than your Utility(residential?) address. I have a similar situation. Did you explain anything about it on your covering letter? Thanks for posting too 👍😄
Another option may be getting specialist medical care in Thailand and using the DTV soft power option. You’d need a medical doctor or specialist to write a letter and have appointment plus in going schedule of care. Goodluck
