Bangalore Metropolitan Transport Corporation [BMTC] — Conductor uses a harsh words on us

Address:

Bangalore,

I travelled in one bmtc bus KA57 F-2540
In this bus, I get in to the bus by talking in mobile phone and searching for seat to sit at that time conductor abuse me with harsh word like first give money then only go and sit, i said ok wait... So he said like always talk in phone no other works for these people, actually am in company call and this man telling like this, is there any rule like dont use phone in bmtc? Or is it a crime to talk in phone when we are in bus?
