Why should he, this isn't the most important matter, of course every longterm visa holder hast to file TM30 and 90 days reporting. Why should someone with longterm Visa and even workpermit have to deal with this, and DTV holders don't? There is no sensible reason.
I habe AXA Thailand as well. Never had any issues with them, very helpful and no prepayment wenn in hospital, just showing member card and all is good.
How long were you in Thailand already before you got the 1 year EoS? I assume you already had your first 90 days while getting the extension if it was based on a non-immigrant O visa
