Bangalore Metropolitan Transport Corporation [BMTC] — not issuing ticket, and not agreeing I have paid money

Sir,
On 5/03/2020 evening I traveled in a bus no KA-01 FA-1430. I give money 5/- for travelling from Gopalan mall to Bilekahalli. Conductor took the money, but didn't issued ticket. I asked him once, he doesn't listened that. When I reached Bilekahalli I asked him for the ticket. Then squad came, again I asked him for ticket for the money which I have paid and suddenly he told I haven't paid money, then squad took penalty of 200/- from me. Just because of this I got insulted infront of every passengers... Just for 5/- I paid 200 as penalty... First time I experienced this and it was a big insult for me... Please do the needful.
