I am using this app from last 3 years till now I didn't face any issue at all. One of the good thing is online booking tickets without a hard copy is acceptable here. Recently they started sending exact location of the bus throught message so it will be helpful for those passenger if they are new in the city and If we enabled whats app option the time of booking we can easily chat with the group for further assistance who already joined the group and almost all the time I got the discount of 3 to 5 % while booking the bus tickets.
