United Bank Of India [UBI] — debit from sb a/c through failed digital txn

Website:

IRCTC next gen online ticketing service

Last evening,[protected], i wanted to buy 2 railway tickets from irctc website online, using ubi debit card with pin option. I filled up all necessary forms. At the time of payment, i used my ubi debit card, giving card no, validity status and then submitted otp. Graphic showed - "your transaction is being processed", and then the screen went blank. After some time, i got a message which informed me about deduction of the exact fare amount of rs. 511.8 from my sb a/c, no[protected] o[censored]bi, berhampore (Wb) 0229, ifsc - utbiobhw206, at 18;43 hours. There were no ticket booking confirmation till now. It was a failed digital txn as the irctc site didn't show the booked ticket. Thus i had to pay for nothing.
So, my humble request to the bank authority, to please look after the matter and solve the technical problem or any other lapse and return my money at the earliest. My name is parthasarathi bhattacharjee, mobile[protected]/ [protected] and e. Mail id - [protected]@gmail.com
Awaiting for your early assistance. Regards.
