State Bank Of India [SBI] — fraud at sbbj bank

I am a saving bank holder in SBBJ bank (A/c [protected])sadul shahar branch 335062 which now has been converted to SBI.
I have been maintaining locker from last one year and sufficient balance so as to pay towards the locker charges.
But in last one year bank has deducted yearly locker charges twice and returned back the same.
When i visited the branch on tuesday i sqw that they have 3200 approx towards locler charges for 2 year including 787 as penalty for delay.
While complaining the same to branch manager he didnt even heared and dismissed our application againat the charges.
Requesting your help.
