PayTM - Fraud Translation on my bank debit card

I have been looted by Paytm, as I believed this as a double secure platform for making online payment.
I lost an amount of Rs:*,**,*** /- on several fraud purchases since Sep-**** to May-****, as this debit card was for business purpose my accounting staff avoided to report me thinking that these all translations was my personal.
Fraud transactions happened with my Syndicate bank account debit card via Paytm.
Below is the transaction description received from the bank>>> ECOM PUR ******** PAYTM, ECOM PUR ******** PAYTM, ECOM PUR ******** PAYTM, ECOM PUR HDFS*I** ONE** COMMUNICA, ECOM PUR HDFS*I** ONE** COMMUNICA, ECOM PUR HDFS*I** ONE** COMMUNICA.
Note that all these transactions are happened without any OTP intimations & also no any bank SMS received for the same.
Now I need to get caught this fraud person who is simply playing with his computer & looting from those peoples who are working hard for their lively hood.
