Got Fined ₹25,000 in New Delhi.

I drive a 2019 RJ14 XUV500 BS4. I went to Delhi to attend a wedding and while coming back the Delhi Police stops my car, checks my documents and fines me ₹25,000 saying BS3 and BS4 is banned in NCR, I'm like yeah alright I didn't know and they proceed to fine me a huge amount of ₹25,000. I really don't think tourist cars should be fined this way. What should I do? What are your opinions Jaipurites?
