In Unit 205 Sanchez says: Elle s’apprêtait à partir - which indicates that she was about to leave, so I interpret this as saying, but I wasn't leaving because I don't like your company (or I don't want to answer your questions); I was leaving for a different reason, which she doesn't get to finish telling us in the next unit.
I could directly translate this as But, not at all ! But that expression doesn't fit well as an answer to his question: Don't you like our company. So, I think the above translation probably conveys the idea best.

Wendy, there are two possibilities:
But that wasn’t why I was leaving.
But I wasn’t leaving (at all?).
I think the most important thing for her is to confirm that she had no intention of leaving.

I think she is saying - But that's not why I was leaving! Is that correct?

France - I have a question.
