Tpsl India — non refund of debited amount for a failed transaction

I have made online transaction for payment of monthly installment for margadarsi chits on 08.04.2019 for an amount of rs.1940 by using my corporation bank debit card. Then the transaction was unsuccessful, but the amount of rs.1940 debited from my account and not received back so far. The narration in the bank pass book is "tech process pg otc no:[protected] margadarsi instal / cn[protected] /[protected]".
