State Bank Of India [SBI] — Wrong information provided or forced to open de-mat account

Address:

712123

I, shubhadeep das have opened an savings account(A/c no:[protected]) on 15th april, 2016 at tribeni branch(00225) by deposit of 8, 500 rupees.

It was told to me from branch(00225) that opening of de-mat account is mandatory from this financial year. So, they have misguided me to open the account & for that already 500/- has been deducted from my savings account.Even it was not told to me that it is chargable.Now tell me how i can get my money back & close the account.
