State Bank Of India — Un-necessary auto debit from my account

Address:

Ranchi, Jharkhand

Dear Sir

I am having an account in SBI Ranchi ( Jharkhand), Account no is: [protected].
on 12th Feb 2015 there was an auto deduction of Rs17 from my account 6 times.The narration column said " Insuf bal ATM Charge decline". To my surprise I had not used my ATM on 12th Feb 2015. Moreover I had never tried to withdraw more than my current account balance.

When I had talked with the SBI representative regarding this, they had advised me to visit my home branch. Since I live in west bengal I cant go and visit their just for this. Kindly address my problem as soon as possible.
