Illegal parking mafia behind sector 51 metro station

I visited one of the restaurants under the sector 51 metro station yesterday. They are charging way more than the average parking rates charged by the Noida authority. And the parking lot isn't even authorised by Noida authority! The audacity of some random Khatana guy to run the parking lot illegally! Just wanted to put it out here. It enraged me but I don't even know what to do about it.
