Ibibo Group / Goibibo — Booking Failed and need refund

I have booked the ticket on the 6th of Sep 2021 from my Goibibo app from my Kanpur to Delhi to Sai Anand Bus, after doing all the process, I had done the payment through phone pay. Then money was deducted but I didn't get any of the ticket on my mail, app, SMS or anywhere. Then I had to purchase the ticket manually from the BUS DEPOT. I need refund and there is customer care available of Goibibo. I didn't receive my money back.
