How much should I be paying in rent if the?

Landlord isn't fixing our stove? It's been a few months now since I made a work order request to get my stove fixed & nothing has been done. They came to measure it & then came back with the new stove but apparently they bought the wrong size. So they left it unplugged & haven't been able to cook for the last 4 days. I pay 1250 a month. I already called the owner or manager in charge of the complex & still nothing. What should I do?
