Paras Tierea: Moved in last month, kuch baatein bilkul unexpected hain

Just moved into my 3 BHK at Paras Tierea last month, Greater Noida West. Honestly, thoda mixed feelings hain. Builder ne kitne promises kiye the amenities ke liye, but ground reality kuch aur hi hai. Power backup ka scene bilkul clear nahi hai, pata nahi full flat pe hai ya sirf common areas pe. Raat ko light jaati hai toh samajh nahi aata kya karein. Aur construction quality bhi... kuch jagah chhote cracks dikh rahe hain already, aur bathroom fittings bhi loose lag rahe hain. Children's play area bhi bas naam ka hai, hardly usable lagta hai. Anyone else living here facing similar issues? Ya yeh sab common hai Greater Noida societies mein? Kya builders sunte hain aise issues?
