Axis Bank — to close saving account from last 2 month

I have the non operating salary account at mumbai branch which converted into saving account. And for nonuse of account i gone to nagpur gandhibag branch to close the account on saying of executive i have deposited 710/- rs on 24/1/18 from which near about 150 rs deducted instantly because of minus account. But after this till date my account not closed and remained balance also deducted. Now i am not liable for pay minimum balance charge and i also want my money back by bank as your executive says returned remaining balance by dd.
And why another branch of same bank take so much time for this type of work another work like deposits are done very fast. And as per law bank will liable to pay for not worked at proper time as 100rs per day
