WHY DOES MY ROOM SMELL SO BAD?

Ok for the past week our toilet has been clogged and we don't know why. We have told our RA about it and she has told security but they didn't come sunday night and they said they couldn't do anything about it. But they did say that they would call the mataince and have them fix it. And yesturday it really started to smell really bad so we kept the door closed until he came today to fix it. and now our room smells worse than before so the whole day I am not going into my room until i know the smell is gone. Hopefully it doesn't happen again and that the smell gets out of the room quickly.
