The staff were extremely rude and were not helpful at all.
Charging facility and WiFi were switched off for the most part of the journey.
Most importantly, they would take you to some shady restaurants which not only have extremely bad facilities (like toilets so dirty it will make you puke) but would also charge you a lot for sub-par quality food. For example, you will pay 200 rupees for a small plate of Veg Biryani which also tastes awful. Also, remember to keep change with you because they won't return your change.
Finally, I would not recommend this bus service to anyone. However, if you still plan to travel by this service, I would recommend you to have your dinner before boarding the bus, keep your mobile full charged, and keep extreme care of your belongings (they board too many unscrupulous elements to fill their seats). Also, in case if you have to get down the bus, be back in 5 min max, because the bus stops for no one and would not even make sure if all passengers have boarded the bus or not before leaving the restaurant or some other shady place.
