here are your options:

1. You can tell them that you wanna go home and hopefully they sent you home;
2. If they refuse, meaning they want you to continue working with them, then you have to finish your contract:
3. You can resign but you have to shoulder your ticket and other expenses;
4. If it is their fault, you can go labor office and hope they'll listen to you and let you go home wherein the company shoulder your ticket.

Depends also what is the real situation!
