*Update*

Suvarnabhumi, connecting flight to Chiang Mai, took about 2 minutes, all he asked was if I have 2 nationalities, and I said yes and told him them (didnt ask to see my other passport) and stamped me in, no other questions, didnt ask about the incorrect name, and sent me straight through :)

My DTV visa was approved, but I noticed they have got my name wrong.

I have a double barrel first name, and submitted my name the same as my passport, however they put my name twice, as first and middle name, which I definitely didn't write

First Name- Rose-Marie

Middle Name- Marie Anne

I guess I wont be allowed to enter with the incorrect name, and have to apply again, but my visa was approved with the incorrect name, will I have issues reapplying, as I'll technically have 2 visas?

P.s I have attempted to call the embassy, they do not answer
