While Tod is most likely correct, some immigration office might not have gotten the message. So my suggestion is, to apply at the most earliest convenience and not wait till last days.
EDIT: so you can consider to try another immigration office. On the other hand, I'm not aware that a "border bounce", aka leaving the country and coming back same day or a few days later would be a problem.
You can do that two times in a calendar year, and the year is closing quickly 😃 already.
As Tod said below. You are awful late. However I have the very best experience with Nakhon Phanom immigration. They are all exceptionally nice and professional people.
Good luck! Funny ... perhaps we meet tomorrow - as I go either tomorrow or Wednesday myself :P
