It's "historique de mes déclarations" (idk if we can speak french in here, since I think you are french too). That's the only thing I can do by myself. I asked for "relevé de compte" to my bank agent but they kept giving me the wrong thing and that p*ssed me off so I just tried with "historique de mes déclarations", is it not goot ?
Not certified but "Documents without an English version is recommended to be translated at an official translation office in Vietnam" so by professional translator I guess. But it's true that paying 100€ for translating very few things like "incoming transfer", "card payment", and "outgoing transfer" is expensive... I already translated myself in like an hour, and by message he said it was correct translation...I'm more worried about giving my account numbers to people honestly.
I have my bank history from 6 months which is 12 pages and another document 1 page. I was asked 270.000 VND / page because they have to translate from french to viet, then viet to english. I visited another shop and the process was the same, they asked me for 230.000 VND / page
