Are these 'hidden' charges normal in Greater Noida projects?

₹95 lakh for my 3BHK in Naya Gaon, Unnati Fortune Group – thought that was it. But possession ke time pe, there were so many hidden costs yaar. Maintenance setup fees, internal electric meter charges, even an 'amenity activation' fee jo pehle nahi bataya tha. Total acquisition cost kaafi upar chala gaya. Has anyone else faced these surprise charges in Greater Noida, especially around Jewar corridor areas? Kya inko pehle se negotiate kar sakte hain ya fix hi hote hain? Seeking advice for next investment.
