I have booked a bus ticket for my mother in prasanna travels for guntur to hyderabad which is ac sleeper bus.
After reaching boarding point they picked my mother in non-ac van upto vijayawada which is very old and seats are not at all comfortable, the best description would be nursey school van.
I have booked ticket for ac bus from guntur to hyderabad and they have provided the passenger non ac bus upto vijayawada which is another city.
I think prasanna travels has done this intentionally without any prior notice and in full aware of that they are gonna do this and they are ok to suffer passengers to save some money.

The legal action should be taken on these type of instances in india for its betterment and development.
