Hidden charges after booking are the biggest rip-off in Noida Extension.

I'm looking at a 2BHK from ATS or Gaursons, budget around ₹80L. They show one price, but then PLC, EDC, maintenance deposit sab add ho jaata hai. Builder toh phone bhi nahi uthate ab. Has anyone faced this with Godrej or ACE? How do you even fight these extra costs, yaara?
