Reporting is only required if you stay for 90 consecutive days in Thailand. If you leave on day 89 or earlier the need to report stops. It will restart at day 1 on your return. Just make sure you have a re-entry permit to keep your allowed to stay date “alive”.
I’ve seen them do either option of changing the stamp or sending them back to the airport. I believe it depends on what’s on the computer system.
Given that immigration is closed until Thursday probably best to slog it back to the airport and get them to change. Immigration on Thursday and probably Friday will just be chaos.
The text in your post with all the misspelling suggests English isn’t your first language, but that’s perfectly fine too. We don’t berate people for that. We answer people who have genuine questions about travel to Thailand and visa requirements.
If you know the answers then please advise. If you’re pissed off that the same type of question is asked everyday then just scroll on.
