VRL Logistics / VRL Group — Bus seat was not sanitized was used by others

I had booked a ticket for 2 from Hubli to Bangalore on Ramdurg-Bangalore sleeper bus. I was surprised to see my seats were allocated to others till Hubli. The other passengers got down at Hubli. After this at least my expectation was that the seats will be sanitized. When asked nobody even cared to losten to my concern. I book VRL thinking it is safe in every way. But after this incident I am thinking its just a hype and VRL is not bothered about passenger safety. At least somebody would have listened to my genuine concern. Very bad service.
