Address:	600001
Website:	www.sbi.co.in

I hold an sbi atm card and used it for transaction thrice on January 3rd btween 10.10 and 10.30 thrice expecting atleast once to get an amount from a jammu and kashmir bank and a federal bank at armenian street. But thrice it was rejected and while expecting no loss to occurred while checking my internet banking i saw that cash has been deducted from the above thrice attempt that amounts to 2000*3=6000. several attempts has been made to contact my branch at iit madras followed by the online complaint registry and the respective toll free number but replying a technical glitch or telling that it could happen to myself(bank staff), no concrete reply has been given from the side of the bank. Kindly look into the matter and help me to take the necessary action.
