Maharashtra Traffic Police — Being fined without a valid reason

I have received a challan fine for rupees 1000 dated December 18th 2021 for speeding when in reality i did not speed at all . I did have an encounter with a traffic police which was because I stopped bit further ahead at a traffic signal because i thought the inspector was waving at me to come forward . And at that time ge told me if I didn't reverse he'll fine me 750 rupees and I did do as he said I reversed back behind the signal line .But today I saw that I was fined rupees 1000 on that day for speeding which is absolutely false and a lie .
