Bangalore Metropolitan Transport Corporation [BMTC] — misbehaviour of conductor against children

Today morning at 11.40 am my 12 year girl was travelling with her younger sister after her exam from kammagondanahalli entrance to rama temple in bmtc bus no. Ka 571- 1378. When she took ticket for rs. 8/- (1 full ticket and a half) the conductor didn't give her back rs. 2/- after giving rs. 10/-. My daughter asked for the balance and the conductor said"wait... Will give later". After the bus reaches the destination she asked again for the balance and the conductor very rudely shouted at my daughter infront of all the passengers with high voice. My daughter felt very sad and ashame and she couldn't reply to him without knowing the local language. This is really a very bad thing to behave like this with two little girls who travell alone in bmtc. The same conductor is always hesitate to give balance to passengers. Please take necessary action against him to don't repeat it again with children. Be
