My Bricksquare possession shocker in Sector 99A

Pre-possession hidden charges in Gurgaon are absolutely ridiculous, ya'ar. Bricksquare Developers in Sector 99A hit me with unexpected IFMS and PLC adjustments at possession. Matlab, kitna unrealistic hai. Did anyone else face this? How much extra did you end up paying for your 3BHK in New Gurgaon?
