Paytm Mobile Solutions — dispute regarding transaction

I want to state that i am a customer of sbi credit card and paytm india. I have received sbi credit card statement for the month of december 2017 (Copy enclosed) wherein amount of rs. 1205/- dated 18.11.2017 has been debited from sbi credit card as i made said transaction. But that transaction has not been made by me.
Therefore i made a request through e-mail to sbi credit card customer care to provide me the id number of that transaction. Sbi credit card customer care team provide me the reference number[protected] dated 18.11.2017 of that transaction with the advice to contact paytm india for clarification about the transaction (Copy enclosed).
Further to this, after going through my paytm account’s track records, i found that i did not make any transaction of said amount with reference number which was provided by sbi customer care team.
Hence, it is requested to kindly resolve this problem, otherwise i definitely approach to consumer court.
