you should be able to call the land lord one more time and be like 'listen this is unlivable conditions, and if i were to call the city about this you would have a LOT more to deal with. either get somebody out here TODAY or I will be calling and finding a service on my own, and you can credit my rent'. he has legal responsibilities to you, and this is not an ok thing to drag out. He can't threaten to evict you or ANYTHING like that for hounding him, although if this is his style management you may want to consider leaving anyway. Good luck, that sucks.
