Traffic Police, Vizag — parking on rk beach road on saturday and sunday

Address:

530002

I'm living in vizag since 5 years near rk beach, recenly the traffic rules on rk beach on weekends has changed. Because of that public was suffering like a lot, especially nonlocal who came to enjoy the vizag. Traffic police are looting them with fines.
I am a victim in one of them, i parked my car opp to vuda children park rk beach, where as no sign boards of "no parking" and no policemen to guide us. When we went to beach and on return my car was towed by traffic towing vehicle. I'm with my wife and two small kids with wet clothes.
When i contacted nearest traffic police, he is reacted very harshly and he is shouting on me and my wife like we did some crime. After some time a traffic police came with vehicle, i requested him to take me to my car, because there is no allow of autos. He is very hesitated and left us. When i contacted traffic inspector over phone, he is also giving warning and trying to threaten me.

Here my question is what mistake i did.
They have not kept the proper sign boards or no policemen to guide us.in return they literally harassed us. After one hour drama one police came to us and took me to my
Vehicle. By the time my two kids are crying like anything and my wife also suffered because we are with wet clothes.

Even there are some other vehicles parked because no signboards, traffic police does same thing.

I don't know where to give complaint but somebody has to teach them a lesson.

When we obeyed the rules they fine us, in reverse what should i do for not giving proper directions and showing power to harrassed me.
