South Bengal State Transport Corporation [SBSTC] — Unfair charges for luggage

I would like to lodge a complaint against the bus conductor of bus no. WB 39B 6713 traveling from Asansol to Karunamoyee starting from Asansol at 2:20 pm. My ticket no. is P[protected]. The bus conductor asked me to pay extra 200/- rupees for luggage as I had a bag which was kept behind the driver seat. On refusing to pay the conductor threatened me that he will throw out my luggage out of the bus in the middle of the street and hence forced me to pay 100/- rupees extra. I only had one bag containing clothes and due to lack of space in the upper carrier I had to keep it behind the driver's seat. I also have sufficient evidence proving the bus conductor charging 100/- rupees extra for luggage and I am ready to provide it as per requirement. I would kindly request you to look into the matter seriously and do the needful at the earliest.
Yours faithfully,
Gourav Biswas
