Kotak Securities — dp charges debit in my trading account.

Dear sir,
While i am checking my leder a/c with you, i am in surprise that you have debited rs.520.38 on 25/09/2018 as dp charges. Let us know what is dp charges & how it is calculated.
I am maintaining my trading a/c with some other reputed broker, where no dp charges on monthly bases are being debited from my a/c, as by you.
Please clearfy the above, so that i may be able to take decision to continue the account with you or not.
Thanks.
