Indian Railways — Poor facilities available -- cockroaches,bugs

We are travelling in AP express from Vijayawada to New Delhi. We are very much disappointed with Indian railways for their facilities. We have booked 2 tier ac, they have charged around Rs. 3000 per ticket. But the facilities provided are even worst than general compartments. We have been seeing cockroaches bugs roaming freely in compartment and even on beds and blankets. Washroom facilities were also worst. When we are paying huge amount per ticket along with the additional taxes and charges, least we expect is cockroaches and bugs around us. Does Indian railways expect us to carry disinfectant sprays along with our luggage everytime we travel?

We are having a terrible experience now. Indian Railways and Hon'ble Railway Minister have to take strict precautions to ensure passengers have a safe and happy journey.
