Indian Overseas Bank — Wrong debit of amount

Address:

560032

I am maintaining my saving account no: [protected] with the Indian Bank, Kanakanagar Branch, Bangalore-560032. on 5th Feb 2016, bank has debited an amount of Rs.1000/- in my account with reference no: 08888100NFSO2015. When i inquired the reason for the debit, bank explains that i have used my card previously before and that transaction has been debited now. I keep checking my transaction carried out as i am a teacher by profession and earn very less salary. I was also surprised to note that on the day i went bank for complaining i noticed that such debits had accrued in few more savings account holders who also had given complaints for the same.
