National Highways Authority Of India [NHAI] — Charging high amount on toll

I want to complain about kherki daula toll plaza. They charge ₹80 when you go to gurugram but they charging same amount ₹80 on return from gurugram. So they are scaming with all the citizens. So this is really wrong and you need to take action against them strictly and fastly. Please take a look on this complaint
Thank you
