PVR Cinemas — Unsuccessful booking

I booked two tickets on Friday 7, May 2022 for an English movie playing on Sat 8 May 2022 at 01:45pm. The booking was not successful, I did not get my tickets or any confirmation whatsoever but the amount 860rupees was deducted from my account.

I went to the PVR lulu mall the next day of the movie, they told me they did not receive anything from my number or email and they cannot find me on their system. They again told them I would get my refund, even now I did not receive anything. Please help.
