Dear @Gurmeet_Dhiman,
It seems the bus conductor told you that online payments are not accepted on Haryana Roadways buses. At the moment, most Haryana Roadways buses only accept cash for tickets, and online payments might not work on all buses.
To find out if online payment is valid, you can call Haryana Roadways at +911722704014 or +919467008780 or visit their website. You can also ask their customer service about this issue for your bus.
If still need help, reply to us.
