How should I go about placing the question mark in a question with a dash?
И где тогда та обещанная весёлая комапния, если Серёга ещё не пришёл, Лёха уже ушёл, а Витя фактически отсутствует – его действительно не поймать ни дома, ни на работе, ни в институте
The question should be about where the весёлая комапния is, which is the first clause in the sentence, but I am a bit reluctant to place the question mark in the end of this sentence as it may look then that the question is about whether it is possible to catch Витя, which is the second clause in the sentence, that is, the one following the dash ( – ).
(Please, don't give me suggestions on how to rephrase my question-example. I myself know how to do that, but I need to know the rules for this particular case. Imagine that this question is a part of transcription, in which you are only allowed to do your own punctuation, but you are not allowed to change or omit words, or change the word order. And, please, don't omit the dash)
