Unhappiness and Unacceptable

I purchased a new home in an estate in Summerset Midrand in December 2017. I have had endless problems within my home and in the estate as a whole from 2017 till current. The walls inside and outside are cracking badly. The floor tiles have come loose. There is water seepage from the ground which is causing the paint to flake and come loose on my walls. There is water seepage from the roof into my garage. Plaster on outside of house is flaking and coming loose. Bath tubs cracked and damaged. Door handles needed replacing after only 5 months. Vanities in bathrooms soiled and damaged after 4 months (was replaced after 2 months) when I first moved in. Boiler room which was our source of hot water was shut down in the complex (due to it not working properly and the estate spending hundreds of thousands of rands to maintain) and each owner had to install their own geysers at their own costs....I could go on and on and on.... Complained to NHBRC and they say its all maintenance issues :-( ..Im living here for ~2.5 years and will have to spend thousands of rands to maintain a brand new house....this is so ridiculous and unacceptable. Please be careful when purchasing a home. Do your homework first.
