Greater Noida buyers, hidden charges aur amenities ka kya haal hai?

Did anyone else get hit with crazy hidden charges at possession? Just moved into my 2BHK in Noida Extension, Gaursons ka project hai. Possession March mein hua tha, aur bhaisaab, builder ne maintenance deposit, IDC, aur club membership ke naam pe jo bill pakdaya, it was almost ₹3.5 lakh extra! Brochure mein toh bas super area dikhate hain, real carpet area ka feeling alag hai. Jo amenities promised thi, jaise swimming pool abhi tak adha bana hai, gym mein bhi bas 2-3 machines hain. Yeh toh bilkul sahi nahi hai. Is this normal with builders like ACE Group or ATS also? Yaar, lagta hai fasa diya. Kya karein ab, koi experience share karega?
