PVR Cinemas — Amount Debited twice but Tickets not booked

I had tried to book for Thunivu movie tickets, 4.15 PM show at PVR VR PXL chennai. I had booked two tickets F6 and F7 which was successful. Then I wanted two more tickets, hence tried to book F13, F14 using the same payment method as earlier (Gpay).The amount of Rs 387.48 was debited from my account but I got an error in my PVR app saying "You are offline and could not be booked". I tried after sometime and again had the same error after the amount was debited. Finally I was able to book using Credit card. An Amount of Rs 387.48 was debited twice from account without successful ticket booking.Kindly look into the issue and refund me at the earliest.
