[Resolved]  HDFC Bank — deduction of amount from my s/b a/c no. [protected]

I am facing problem of deduction of amount from my s/b a/c no. [protected] each month of rs 708/- from may 2018 to oct 2018. I am tring to keep my account balance more than 10000/- still there is debit of above amount.
When i asked the reason of deduction, it was informed me that minimum balance should be 25000/-. It was never informed me in advance that minimum balance should be 25000/-. I am having another s/b account in hdfc bank, but there it was told that minimum balance should be 10000/-.
I am unable to understand the requirement of your bank, kindly explain me immidiately because already i have lost rs. 3540/- of my hard earn money.
