Sdmc — unprecedented parking charge

Address:

New Delhi, Delhi

Parked vehicle in haujkhas village parking for 40 mins, they charged my sister 100 rs.
When they raised their concerns, parking people behaved badly and argued.
4-5 goons type people roaming around and all saying this is the rate and you have to pay, go where you want to complain.
Major concern is behaving badly with females only in car on illegal parking charges.
As i aware, its 20 rs per hour but they charging illegally and i hope sdmc will take some action
