its horrible. I thought my source is chebrolu in west godhavari. But when call bus attender it chebrolu near guntur. I asked him to cancel the ticket. He said ask to who issued the ticket. I called from site no of kaveri, ask redbus. I checked the no from redbus ticket mailed to me. It does not have std code and not worked. After i tried from redbus app contact no. I tried several times after few times call support person attended my call and said by this time we cant cancel the ticket. The red bus app not showing history of last booked tickets. but it showing last 5 months back booked ticket. App may have problem in new version. And if app have cancellation option then its better. I called the bus attender, and i am not able to come because its 100 kms distance from my place. So i postfoned my journey.
