While making a transaction on 29th August and two transaction 16th of october 2016 through SBI atm, i was not sure about the exact amount in my bank account as it is not my salary account and i rarely use it. So i entered an amount which was higher than the amount in my bank account . Thereafter i entered a lower amount and was able to make the transaction.
Next day when i checked my account statement, i realised that SBI has deducted Rs 23 which a remark saying "Insufficient Balance ATM decline charges". I was shocked to see that they have deducted charges for entering an amount higher than the available amount while making an ATM transaction, which is so lame as a person does not always remember the exact amount in his/her bank account.
I already mailed SBI about the issue but they did not reply back. Therefore, i request consumer complaints to help me resolve the issue at the earliest.
