New flat, new problems: Builder ka hidden cost drama

Just moved into my flat last month near the Top Builders corridor, aur abhi se itna frustration ho raha hai. Builder ne brochure mein metro connectivity aur smooth roads ka bahut hype kiya tha. But society mein move-in kiya toh pata chala, maintenance ke naam pe extra charges laga rahe hain. Bolte hain 'infrastructure development' ke wajah se cost badh gaya hai. Matlab, ₹15K extra har quarter for what? Is this normal? Kya Top Builders area mein aur kisi ke saath bhi aisa hua hai? Hidden costs after possession, kya karein iska?
