I am highly disappointed from your side as consumer complaints are not being resolved!!!
I am posting this complaint for the 3rd time and this still remains unresolved

On 16th feb, 2018i have booked a ticket from jaipur to pune but the transaction failed. Money is being deducted but no money has been credited to the bank.
The irctc site is showing refund status as "refunded" but no money is credited from irctc to the bank.
1. Cancellation id/refund id [protected]
Refund amt 1520

Please let me know what is the issue and till when the amount shall be credited to bank.
And irctc has also assigned ticket id [irctc #8143446]

In the subject line of all future correspondence about this issue.
