Unhappy with maintenance

I moved in on of Zelri Properties in Soweto the name of the complex is Orlando Towers Lifestyle Estate. I moved in on the 27th of March. Ive been sending emails regarding maintenance, calling and using the *** website but I never get assistance. Im so disappointed because these are new developments and I was expecting the best service. Lately, I have an issue of electric plugs that are not working. I never get reach of them, they only reply when I send them the rental ***. Im so hurt and disappointed. I think the best option now is to move out.
