Prestige Group communication is totally broken

My current 2BHK in Bellandur feels too small now, but this builder drama is endless. Prestige City ke liye booking kiya tha, OC ka kuch pata hi nahi chal raha. Customer support phone hi nahi uthata. Keya Life By The Lake ka bhi yahi haal hai kya? Mera home loan chal raha hai, aur ye log bas ghumate hain. Anyone else dealing with this silence?
