Bangalore Metropolitan Transport Corporation [BMTC] — Peenya metro station staff(exit booth) behaviour and swearing against me.

I m new to Bangalore city, I visited my friends in Mantri square and heading back to my pg (which is located at Peenya). I gave 50 rupees and asked for metro to Peenya, the staff gave me two coins. Since I m new to metro. I thought it was supposed give 1 at each station and there i found that people were scanning and did the same, then I thought staff had mistakenly given me two. Moving on, in peenya metro station metro gate. The token didn’t work, the staff asked me to pay 3 rupees to pass. I questioned them why, there were two woman and one man. This man came out of the cabin asked me if I was drunk. I got offended and asked him to take a drug test. He started screaming and swearing in Kannada and told me “You ugly ### had come to work here, you don’t tell me what to do”. Then I told I’ll pay the amount and told him not to speak like this, he again said “boli maga beverse” (it is a bad word in Kannada). Then, when I asked for his name, he pulled out the phone and started taking pictures of me. I request you to kindly go through the security footage and take action against that man. I assure you that, I’ll give my full cooperation against this.
