What should I do if my credit report shows an eviction from an apartment that was inhabitable due to garbage disposal backflow?

I had a apartment manager refuse to consider the garbage disposal backflow from my neighbor an emergency. My bathtub was filled with garbage disposal contents that gave my entire apartment this unbearable horrible smell. You couldn't even breath without wanting to vomit. The manage said I would have to wait until after the 4 day weekend because he said it's not an emergency. The odor was so and that my girlfriend, roommate and I had to stay at a hotel. When we returned the problem was not fixed so I told the manager again. He said the repair guy will get to it when he is done with this other repair . I told him that I couldn't stay there because it was a health hazard. When the problem wasn't fixed the next day we moved out. now my credit shows an eviction.
