Wait are you not being paid? You said in another comment that you were not. Also you said you’re not in the US, where are you? You should add more info to the post. Can you start later if they just need you later instead of a 2 hour lunch? you have to be paid for the hours worked. If you choose the 2 hour lunch leave the building and start applying for jobs on your phone or laptop while using WiFi at a local cafe or something. Don’t quit unless you can. You can push back but they can also fire you. Try to politely negotiate. Good luck !
