I don't think (e) is helpful. Have you moved out into a hotel room or different apartment (see (f))? They probably reset the 7 day clock in (c) each time someone shows up to make a repair. If they get pushed, I suspect they might say their records indicate each time a problem was reported, they addressed it within 7 days and you are still living in the apartment, so...

As it sounds like you plan to do, I think you should have a professional / constructive discussion without threats.
