Each month sbi childangi branch (Ifsc sbin0006581) is deducting some arbitrary money as od charge even though i pay the interest on 1st of each month. Last month (30/11/2018) they deducted rs 394 mentioning "od pnl intt". Bank manager is unable to answer my query. Please refund the amount that was wrongly deducted for last few months.
