ive had maintenance staff at property mgmt company do repairs but i basically had to hound the company repeatedly, in once case for a year, had to take photos of the broken thing in question and send it to them in writing in email, so there would be record of it, so they would be afraid of me pursuing it legally and having it substracted from rent. also, it helped that i got to know the maintenance staff and tried to keep a good relationship with them and be sociable, as that seemed to help get priority, as they are often very overworked

in some cases (like plumbing repairs ) I cannot arrange a plumber to do it because they are not allowed to by law in the region where i was at but they did respond to emergency number when i called at least and the maintenance guy got some overtime for it, so that seemed to work.

that said in most cases the hassle was so much that I would just perform the repair myself, which is really what they hope you do. I second hand know it sucks to be disabled and have to relly on the company to fix anything because I've heard so many horror stories and complaints about that before
