So, after a little bit of online stalking I'm supposing that you're on Koh Tao. This is the new office just opened up there. They are a subordinate to Surat Thani Immigration.
Like their office in KPNG, looks like they are applying the 90 day rule for anyone on an extension of stay and who have been in country over 90 days. The report is free and doesn't take long to do.
