Karnataka State Road Transport Corporation [Ksrtc] — Staff behaviour is rude

As we noticed there was no seats available in the ksrtc bus only last row was there but due to health issues and conditions it was quite not safe, so reported this to ticket counter women to either cancel this ticket or to give the ticket of next bus, so that we can choose our seats but she reacted very badly and replied in a very rude way, and just because amount was paid, i am supposed to sit in last row which is quite unhygienic as well, literally very disappointed and dissatisfied with this service.
