Non-B renewal: teaching license documentation

My Non-B visa will expire December 19. 

I need to attain my Thai teaching license and work permit prior to renewing the Non-B, but have been denied the license without the physical degree.

I graduate with my BA Dec 13, yet it will not be reflected on official documents until December 18, and I will not receive the degree until the end of January. My university provided a letter from the Dean's office stating my enrollment status, along with my unofficial transcripts to show projected completion of the BA before visa expiration, and it was still denied. 

Does anyone have advice on what to do to attain the license, retain my Non-B, or bridge the gap without overstay or amnesty?

Thank you
