well, as far I know, to fill and send the TM11 can take around 7 days to be processed, and I think you have to be "under the authorities" until it get solve. I THINK, NOT SURE, GOOD IF SOMEONE TEACHES US IN THIS
Well guys, it happenned to me a month ago and now I am in my country. It was in Suvarnabumi also, totally same situation. In my personal opinion it is useless to try arguing with them. They probably put a stamp in your passport and write the clause number 2. Next, they will take you to an small room with other people to be awaiting for the airline staff. Dont get in panic, call your embassy just to let them know you are inside there and why. If everything is ok, tomorrow or even today, because is early yet, you will be in a flight to your origin airport. Once there, think about what to do. But important, dont be agressive with them
