Missed an important meeting with my lecturer!?

I was supposed to submit a course work long time ago, but I didn't, so my lecturer sent me an email telling that I should meet him urgently today afternoon, so he can look into my issue and give me a chance, and because i didn't sleep the previous night, I over slept and missed the meeting, I've got an email from him telling that he awarded me a zero mark for not turning up. what do I do to make this work again?
