Bad customer service

We moved in June 2018,but received the key May 18 I believe . We signed a happy letter because we were so happy to be home owners. With in 6 months of moving in we saw cracks in most places of the house and geyser switch kept on tripping . We reported that and they came and fixed it . But then again there was another issue. Roof was leaking and pipe on the kitchen sink started showing leaks . They advised the roof must be claimed from insurance. Insurance report came back to say its negligence from the development. They then came and fixed the roof .but did not fix the plumbing fault . We installed a new kitchen builtin and now the leak is all over the kitchen side . I reported this more than 3 times .with no solution. I stay in house 102 . I reported all these incidents to Jackson. Now our kitchen is messed up because of their negligence in plumbing. Wall outside looks like it can fall anytime . For a house that is less than 3 years old
