Indian Railways — complaint regarding misconduct of tt squad at majestic /city railway station bengaluru

I was travelling with family from tirupathi to bengaluru on 2nd jan 2020 via sheshadri express. After getting down at bengaluru by 1.10 pm squad fined me because of no ticket to my son. Who is 9 years. I asked rules then lady tt told i[censored] speak nicely i will charge 60 (Normal ticket) plus 240 as fine i[censored] speak more or argue i will charge 150 + 240 fine. They charged me 390. If i am guilty then train tc will be guilty if he ask or check that time only i may pay 60 only. Team of 3 dangerous ladies who r arguing and using bad language. They told they u can not anything against us. Just they checked for 20 minutes only later on they went from that place.in this matter i want to complaint that kindly give full-time official work of checking the tickets. What r their timings? They r behaving as like railway is their entire property. Very sad. At all the stations give duties to to these tt or squad to check. What is the rules of speaking in low volume or asking rules to them. Kindly enquire the same with tt. Two squad ladies are overweight and not have patience to even answer. Previously they use to get lot of money but now everybody is ready to find and want receipt. I asked her to take 60 as fine then she told that your r speaking lot hence we will charge you 390. What is this rule?.
