South Bengal State Transport Corporation [SBSTC] — cash for luggage

I with my family board on the bus no. Wb39a 1634 from santragachi. I am on bus now. The conductor has charged an extra amount of rs.100/- for which he is not giving me any ticket for my suitcase. I called at the complaint phone number but no one picked it up. At shaktigarh the conductor and driver shared the money. Please take necessary steps while just i crossed galsi.
Nb. Although we don't got any seat and i am sitting on the engine beside the driver.
