Mahagun ki possession par itne hidden charges kyun?

Just got possession of my 3BHK in Crossings Republik from Mahagun last month. Honestly, the final bill was a shocker. They added so many 'miscellaneous' charges, yaar. Had to pay extra for PLC, EDC, aur phir kuch weird 'club membership' deposit jo pehle kabhi bataya nahi tha. It felt like they just sprung it on us last minute. Aur ab maintenance charges bhi itne high hain. Anyone else faced this with Mahagun ya other builders like Gaurs in Ghaziabad? Kya karein iska?
