<human>: Kansas City Missouri

3 months ago my apartment was broken into, this scared the shit out of me and my wife. Nothing was stolen, just the people left some really creepy stuff around. After this happened we asked the landlord to replace the two locks in our apartment, the one to apartment building and the one to our apartment. They waited 3 days to replace the lock on our apartment door, then waiting two months they took the door off our building and replaced with one that didn't have a lock.

Last weekend our apartment was broken into and damaged, by someone with a fuckton of malice. There was holes put into the wall and a fire dropped in our dogs kennel. (He managed to get out of the kennel to hide under our bed) We come home only 2 hours after leaving home, and our apartment hallway is vaguely smokey to the point you can smell it and see it on the ceiling. We open our apartment door and find out the apartment is filled with smoke hanging in the top half of the apartment. It looks like our dog is missing and we frantically search for him to find him under the bed. We're scared. We call the cops, and start figuring out what to do. Call our renter's insurance. Theres a black spot in our puppy's kennel and on the carpet after he flipped it. 

Cops show up 5 hours later. inspect the damage and give us a police report. We go to our landlord the next day saying we want to break our lease, because there was a fire in our apartment and the fucking smoke detectors didn't go off, not to mention the other security crap. She says she has to talk to our boss and then she calls telling us we have a notice to vacate at the end of September. Oh and I reported that the smoke detectors in the hallway were out of batteries a week before and nothing was done.

It should be said that me and my wife have gotten into 3 or 4 really heated arguments the past week so they have that.

Can you summarize the given text in a few sentences?
<bot>: Apartment broken into twice in 3 months. Maitanence makes us more vulnerable than we should. We want to break lease, given a notice to vacate.
