Tamil Nadu State Transport Corporation [TNSTC] — TNSTC Conductor bad behaviour

Address:

State Express Transport Corporation Tamil Nadu Ltd., Head Office, Thiruvalluvar House, Pallavan Salai, Chennai – 600002.

Today (04/09/22) I travelled from coimbatore to kozhinjampara in TNSTC bus (registration number - TN38 N2925).
I handed the conductor a 500 rupee note as I failed to bring any change. He suddenly bursted out and started to scold me raising his voice. He even threatened me to throw out of the bus. He mocked me that I'm a keralite and I don't belong in Tamilnadu. I searched all over internet to file the complaint. But the contact numbers didn't connect to the relevant office. Please take necessary actions
