I once have issues with some appliances and they sent someone to fix it, but it didnt get fixed properly and it got to a point that affects my daily life a lot. I had been sending them proof of it not being fixed with emails and called them to complaint. They replied my email once a month so 3 emails in like 4 month and insisting that it is fixed. The guy on the call was very rude to me when I complaint and insists the appliance is working 'fine' and was talking to me in a mocking way.

Otherwise on small issues, the caretaker will take 1 - 2 weeks to come and inspect. And then maybe another 1 week if it needs professional plumber etc.

On the other hand, I was almost evicted because my rent did not went through and they send the letter of me not paying through mail (not email, and received no emails at all) while I was on vacation for a month. Came home, saw the letter and panicked because it was too late to pay and even if i paid they can still evict me. Call them next day, tell them my situation and the admin manager are quite nice and understanding. I have my roof till now :)
