Broken toilet bowl, landlord not responding.

[Jennifer Hunter]

Hello. I recently moved into a studio and immediately noticed that the toilet bowl is cracked, it is not bolted to the floor, and is leaking from multiple spots. I am shocked that they allowed anyone to use this toilet, it feels incredibly unsafe. I've emailed the landlord, with pictures, 3 times about this situation, and have not gotten a response. I don't know what to do. I feel that the toilet could break every time I or my friends use it. If you have any advice, I'd gratefully appreciate it.
