I re-entered Thailand via BKK on my yearly extension of a Non-B visa about a week ago. After getting back home to Chiang Mai, I noticed that the official has written the wrong date on the "until.."-part of the entry stamp by a month.
Do I have any other options than returning to BKK airport to get the mistake corrected? Tried calling Suvarnabhumi immigration but nobody picks up the phone.
ps. Yes, lesson learned, always check your stamps immediately after receiving them.
