As you are aware redbus.in is one of the most promising and fast growing website. All the credit goes to the employees working in customer care and digital department.
As per my friend: He told this "Get in touch with this organization in quick time and get the positive results that you are pining in order to make your commercial activities gain measures in the search engine!" So I personally even use it for all my domestic tours because of it’s variety of travel agents and lowest prices. A big thumbs up!
