Airport Wings — parking charge

Address:

Jaipur international airport parking, Jaipur, Rajasthan

I went to jaipur airport to pick up a passenger by my car rj14td0592 on 11/09/2019 at 19:00:17. At entry gate they gave me a free ticket valid for 8 minutes exit. I reached at exit gate after 7 minutes but they stopped me to wait at gate and completed 8 minutes and charged late fees 85/- illegally. I want to take a action on airport parking authority jaipur and solve my problem.
