Cubbon Park 3BHK buyers: Builder delays are frustrating!

₹1.8 crore for a 3BHK near Cubbon Park was already a stretch, but now this builder delay is driving me crazy. 2.5 years ho gaye, still no OC, aur kids ke school admissions ka tension alag. They promised possession 6 months back, but ab bolte hain 'minor approvals pending'. Matlab, why can't they be upfront? My wife is so worried about the neighbourhood safety for children, aur abhi tak project finish hi nahi hua. Anyone else facing this with builders in this central area? Did you find any hidden costs later?
