Future World's Sector 44 charges are misleading

Reviewed Future World's offer in Sector 44. Their ₹1.8 Cr quote for a 3BHK seems fine, but the 'miscellaneous' and 'utility setup' charges are vague and substantial. These hidden costs really inflate the effective ROI. Has anyone managed to get these ambiguous charges reduced with Future World or other Noida builders? It's impacting my total cost calculation.
