Correct .. I lost it changing trains along with phone. I knew within few minutes I had made the mistake and cancelled it immediately. I had no funds to move for a few days so walked to police station after 4 days and they would not do it without embo letter
buy the cheapest one way ticket outta Thailand you can find . Bangkok to Kuala Lumpur or Phnom phen $40-50 if booked in advance. Get a ticket you can cancel or buy a dummy ticket.. I've never had an issue using dummy tickets though no doubt someone has.
