@Tod ********
i can try to get a TM30 from Bkk except that my landlord won’t help (but that’s another issue); i just thought it would be easier in Prachin where my gf owns a house (I kind of share my time between both places).
As for appealing, the more I insisted, the weirder the answers got. As i will be in Vietnam on 26-27 (a weekend), i was told to apply for a visa there during my stay (sic), then i was told i could not apply for extension in Thailand anyway, etc. I think that IO was uncomfortable being confronted with a new case and just wanted the issue to be dealt with somewhere else by someone else.
