Ghaziabad builders: What's the real amenities story?

Raj Nagar Extension mein 3BHK dekh raha hoon family ke liye, kids ke school pass. Gaurs, ATS, Gulshan Homz short-list kiye hain. Inki construction quality aur post-booking customer support kaisa hai? Jo amenities promise karte hain, woh actually milte hain ya sirf paper pe? Please share real experiences with these Ghaziabad builders.
