Indian Bank — amount not credited for the failed online transaction

Dear sir,
I wish to introduce myself as beena b. M., bearing a sb account in indian bank with the sb account number :[protected] at nhce, marathahalli branch, bengaluru.

On saturday, 03.03.2018 at 11.33a. M, i was doing online money transaction of rs. 15, 000/- through my debit card to an institute "datamites". The transaction was declined and the amount rs. 15, 000/- has been deducted. Immediately, i got sms in my mobile below:
Withdrawal of inr 15, 000 ac xxx124207 drawn the pos id:38r00010 on 03/03 at 11:33:47. Cl bal: 45, 083.09 cr - indian bank. The same amount has not been credited back to my account till date.

Since the transaction was declined for the first time, i did the online money transaction again through my debit card and the payment was successful and amount of rs. 15, 000/- has been deducted. And, i got the sms in my mobile as below:
Withdrawal of inr 15, 000 ac xxx124207 drawn the pos id:70018176 on 03/03 at 11:37:51. Cl bal: 30, 083.09 cr - indian bank.

The amount for the pos id:38r00010 on 03/03 at 11:33:47 has not been credited yet and i request you to kindly credit the amount of rs.15, 000/- for which the transaction was declined, fix this issue as soon as possible and oblige.

Regards,
Dr. Beena b. M.
