Over the past three months, me and a few of my roommates have been frustrated with our other roommate. She likes the apartment SUPER cold, and because of that, our utility bill is higher than my parents bill. She won't budge on the temperature and won't compromise either. Also, she and the girl who shares a room with her refuse to help keep the apartment clean. We tried writing up a job chart, but they took their names off. The bathroom is disgusting--you can't even see the countertop anymore. What should I do??
