i heard from my known people that the builder troubles a lot after selling and before possission? i am looking for a home in that area. is it true that builder is money maniac and never responds after sale?

We have brought a house in Praneeth Pranav Homes, Beeramguda. My sincere feedback is never buy a property in Praneeth developers ventures because of following reasons.
Poor quality of constructions cracks will appear every wall of the house not sure what material they use. Masons, electricians, plumbers are very very poor skilled they don't know have any previous experience so you can expect that no wall will be straight or well finished. Electric points well be on gods mercy if your light will actual work when you install the buld or plug point. Builder will show you seventh heaven when your purchasing the house saying swimming pool, full loaded club house, children's play area and many other promises, honestly that will all be on builders mercy because not sure he can actual provide them,
My 2 cents is never go with the developer if you are looking for your dream house or you have to put double the money that you purchased the house to fix other problems.
