One97 Communications — Ticket didnot booked but money debited from credit card

Dear sir/madam
I had booked two tickets from lokmanyatilak t (Ltt) to varanasi jn (Bsb) for irctc rail tickets, from my saraswat credit card (Nikhil makwana), on 21/05/2020. But due to network problem we received otp a little late. After entering otp, it was taking too much time for processing and after that screen is totally blank. Does not received any tickets and also message. But the money rs.3556.38, was debited from saraswat bank credit card. Again i booked ticket and again deducted money from card and got ticket.
Kindly help me. Please refund my money.
The 2 massage that i received:
"tranx of rs.3598.34 ising credit card is made at irctc noida upin on[protected] at 14:35 (In this tranx i got confirmed ticket)."
"tranx of rs.3598.34 ising credit card is made at one97communication ltd delhi dlin on[protected] at 14:37 (Tarnx no. Z[protected] in this tranx i not recd any ticket and debit amount)."

With regards
Nikhil makwana
