What is ksec in kotak bank?

Auto-debit is a facility which facilitates automatic transfer of funds from your linked Bank account to Kotak Securities on a specified date instead of having to manually transfer the amount. From my account money is automatically transferred to KSEC (Kotak Mahindra Bank) as fees and margin. 10k got transferred to KSEC(Amount deducted). My 5L money got transferred to KSEC fund without my consent. Hi dear sir/madam, Today 23/02/2020, in my kotak bank account has been debited 100/- to ksec, Without intimation funds transferred, kindly.
