Amrapali's hidden charges at possession - is it normal?

Amrapali Green Valley mein, they quoted one price, but possession ke time, PLC and EDC mila ke almost 2 lakh extra nikal gaya! Honestly, I had no idea about these charges. My parents keep saying builder log loot te hai. Is it legal to charge this much extra? Anyone else faced similar issues with Amrapali? What did you guys do? Ab samajh nahi aa raha. Is it worth fighting this?
