My Sarjapur Road 2BHK: hidden costs at possession

Hidden charges at possession for my new flat were a rude awakening, yaar. Finally got possession of my 2BHK in Sarjapur Road last month, it's a Godrej project. We were so excited, everything looked perfect on paper. But jab final bill aaya, it had so many extra charges like PLC, maintenance deposits, registry fees jo pehle bataya nahi tha. Is this common for other big builders like Prestige ya Sobha also? Feeling a bit conned, tbh. What was your experience with hidden costs at possession? Did you face similar surprises with your project?
