Tamil Nadu State Transport Corporation [TNSTC] — Over charged in bus ticket

Address:

Chennai

I'm a student, studying in Chennai. My home town is Tiruvannamalai. Every week I'll travel to Tiruvannamalai. On 24.01.2024 while travelling I was over charged than normal bus fare. Usually the bus fare would be 175 for normal bus and 205 for AC bus. That was a poornami day so bus all came rush. So from the bus depo sent a Local MTC bus for a long which itself a mistake. On that bus only I travelled they charged me 200 to Tiruvannamalai. That fare is equal to AC bus fare but they charged that for local bus.
The Local bus number I travelled is AMJ 1928. I asked to that conductor he's said the depo asked him to charge this price. This is a crime. Kindly go through this issue and refund my overcharged amount. I hope you'll do.
