terrible service delivery

I was an official occupant of the apartment on the 10th of April 2015, and was promised that all the necessary maintance will be attended to ASAP, its 3 weeks later and I still have no lights in the bedroom. Several other things are also in questionable condition. I had then sent the Agent emails and tried calling and still no response or reply. I then contacted the company directly, they said they would comtact me, nothing happened I called in several more times,with no luck. This is really unacceptable, taking into account that I will still be paying rent for a place with no lights!!
