Rto India — Penalty for parking on footpath

Address:

Pune, Maharashtra, 411027

I have parked my vehicle(two wheeler) in front of central in pimpri chinchwad on footpath, as it is not in much use and other vehicles were parked there as well. It is picked up by RTO people and when I went there to collect my vehicle they have asked for Rs 1000/-. And they have shown the chart as well, where the penalty for parking on footpath was mentioned as Rs 1000/-. Now I came to know it is Rs 100 only. It must be their daily routine to deceive people everyday. How can it be tackled, where should I complain?
