Legal/Banking Advice Needed

In my CIBIL report i can see one loan account from IDFC registered on my account (2yrs old consumer loan account). Though it is paid timely but it's not mine.

And I have never had an account with IDFC in my entire life and the amount is very less only 13k.

1. What measures should i take to remove that account from my name or from the CIBIL report?
2. How to know the account number? Might be needed to share with the bank..

Also, is there any way to check how many credit cards or loan accounts are in my name currently or in past?
