Horrible Landlord

I have a big problem with my landlord,he doesn’t want a exterminator in my apartment where I rent,i have a 10 month old daughter and a 5 year old son.I have a mice infestation apartment,i can’t even let my 10 month old daughter learn how to walk because there are so many mouses i don’t want her to be on the floor. So now he finds out I reported the problem to the city of New York about not having an exterminator.

The landlord threatens me with a notice of termination letter sating I have to be out of the apartment by September 20,2008. The letter was not notarized. I don’t owe him no rent I have all of my proof. He can’t kick me out of my apartment just like that,I called and asked him why he wants me out of my apartment he told me because I complain to much. this landlord is horrible and I need to no what I should do from here.

What’s your landlord’s name so I know to possibly avoid him/her!
