I don't know / I don't understand.

[Cécile]

I was taught last week how to say "I don't know and/or I don't understand in chinese". A french woman who is learning chinese told me she saw two chinese women in the underground and that they said something she understood! She was very proud and tried to teach me the sentence she understood, that was "I don't know" or "I don't understand".But I forgot everything...
Could you tell me how we're supposed to pronounce it, too?
Thank very much!
