Bangalore Traffic — Charged fine didn't give challan.

Yesterday while coming from hospital I was stopped by traffic police despite of me following all the protocol.i provided all the documents still he asked me fine for some queries he talked in Kannada which I didn't understand.
After giving 1000 when I asked for challan he refused to give rather got aggregated and asked keep my bike here.

Overall its been really bad experience from past 5 years in Bangalore.Such corrupted police I have not seen anywhere.
