There are a couple of things your can do. Every successful booking will have an
e-ticket sent over email on the registered E-mail ID given during booking. In
case you have not received the e-ticket over email, you can also check for
Whatsapp & SMS confirmation of the PNR and other ticket details.

You could also check on the Wizzride App :

Go to Menu, then My Wizzride Bookings, under the Upcoming Tab, if the
booking you made is still not visible, contact support with your transaction
reference and registered mobile number. Wizzride team will verify the
payment and assist with the booking/e-ticket.
