Bank Of Baroda — Bad Cibil report due to Bank of Baroda

Address: Mumbai City, Maharashtra, 400059

In 2007 I had signed as witness for a friend call Hema Bhatija for 50000 loan amount. When I pulled my cibil report recently I came across that my scores are gone down because of Bank of Baroda Its shows that I have pending loan of 43000rs. The Bank needs to do the follow up with the person who had taken the loan and without informing me I found my cibil scores were down.
The person whom I have signed does not exists and no contract with that person.
Kindly investigate the same. As per my cibil report the account number is SION[protected].
Let me know how do I remove this from my cibil.
Please call me on [protected]
