Waar heb je het over gast? Ik ken je niet, ik weet niet waar je vandaan komt, en verteld geen naam of waneer dat dan gebeurt zou moeten zijn. Wat moet ik daar mee?
What are you talking about man? I do not know you, I do not know where you come from, and you did not mention any name or when that should have happened. What should I do with it?
The way I read the Dutch sentence, I think what is meant is 'you didn't mention...'. But either way (I or you) it is a bit of a guess because the Dutch sentence in incomplete. I would, however, put the other option in the remarks.
