I would like to know do I have just cause to break a least agreement?

I moved in my apartment on 07/07,on 07/18 I had to do a noise complaint. On 07/24 I had to do another noise complaint on a different apartment. On 08/08 I walked in the office and made a verbal complaint and my neighbor having a dog on are shared porch. The neighbor placed dog pads out by my door for the dog the never cleaned up after the dog. On 08/10 I did a 2nd verbal complaint. Most of the feces were cleaned up on 8/21,but as of 24 there's still dog feces still on the porch. I can't go on the porch and it's hard to cook without opening the door to let out steam. I expressed this in both verbal complaints. Also both apartments make noise after midnight. I have pictures,audio and a log. I also done a verbal complaint on 8/13 about guys sitting on my AC unit. Now,I fear for my son and my safety because on 8/21 I seen a man go to his friend house,pulling a semi rifle out his car. He's does this Everytime he comes here. Word is him and another man is having problems.
