My 2BHK final cost shocker near Residency Road

Okay, I'll be honest — I completely underestimated the final costs for my 2BHK in a Prestige Group project near Residency Road. Just got possession last month, and the initial 1.3 Cr price ballooned. Suddenly there were charges for PLC, parking, some 'utility setup' fee, and then OC/CC processing. My 2BHK is now pushing 1.5 Cr easily. Things nobody told me upfront. Did anyone else get blindsided like this? Feeling really cheated on the final amount. How do you even get a *true* all-in cost before signing?
