From the comments I can assume you were rejected for using a Thai bank account. If I were you Iβd take the hit on the 10k fee and apply again using a foreign bank account as proof of savings π
I know ππ€¦ββοΈ I paid an extra Β£100 for a flexi ticket, but I guess worst case if you get rejected you can still visit on a visa exemption for 60 days
Where are you based? Highly recommend Singpatong Sitnumnoi in Phuket.
Itβs all done on by yourself their website site they make it very simple, then immediately when you pay they send an email with all documentation needed for your dtv application π
