Thanks everyone for contributing with your views, helped a lot! I felt completely lonely in this situation, once I got into it no way to get out. Had to work in the apartment (full of mold) for 2.5 months more than full-time at the same time as I had these dental issues (and still have, the supplements and homeopathic I got are only temporary). I lived in Taichung 2 months earlier, although during summer, liked it better. Perhaps Kaohsiung is also bettern than Taipei (I've heard a lot of people move from Taipei and choose to live in Taichung instead). Anyway, this was my last time in Taiwan, any reason I would visit would be to see this holistic dentist.
The landlord first said she would visit me, then when I complained about this said she would send the housekeeper at 08.30 Sunday morning. She never turned up. So I made a quick decision yesterday and changed my flight to Sunday evening. The security guard downstairs (really weird atmosphere all the time, the landlord told me not to talk too often with them for some reason, but instead choose to talk to the housekeeper, who tried as much as she could to avoid having anything with me to do), when I left he didn't open the main entrance at first (normally does that immediately), but instead called my landlord, after that he let me out.
Some pecularities in the rental agreement also: Must show respect to the security guards (always greet them, not in the contract that you must greet them, but you couldn't avoid it), always must register visitors, maximum 2 persons allowed, fines if you don't do proper recycling etc. Often when I just have my job in my mind and go out, it doesn't feel like you want to greet a guard, I don't consider myself disrespectul for that.
I didn't have time to do anything with the things I had bought, so I just left them as they were in the apartment.
