Chander Nagar possession: Hidden charges ka kya karein?

Possession was in March for my Chander Nagar flat with Deepak Kumar, aur abhi bhi bohot gussa aa raha hai. They said all-inclusive price but then ₹75k extra for 'utility connection' and 'club membership activation' just before handover. Seriously, things nobody told me. My EMI chaloo ho gayi hai, aur upar se yeh hidden charges. Kya ye sab standard hai ya builder ne game kiya? Has anyone else faced such last-minute costs? Matlab, how to avoid these next time? Is there any way to fight these after signing?
