Website:	Railyatri

I booked a bus from hosur to chennai on 22nd feb 2020 10pm 4seats but due to seat upper bearth selection i cancelled seats. But during cancellation through intercity travel app selected wrongly bus was cancelled by operator selection on 19th feb 2020. I informed earlier but no action they simple telling due to your mistake amount can't be refunded. Customer care not ready to ear my problem they every time cutting phone line during explaining the issue.
Poor customer service.
