FORGED DOCUMENTS & SIGNATURE for loan

Recently a loan has been reflected in my CIBIL & it shows that EMI moratorium has been done on the same which I have never taken or applied for. I learned about this loan after this only. I enquired the with your customer care of bank. I personally visited Bank loan Center. The customer care executive told me that this loan has been taken by my husband 8/9 years back ( we live separately from 2.5 yrs) by submitting my documents as Jt. account holder& my forged document & signatures have been done on all documents. The executive denied showing me any documents related to this loan & told me that restructuring of this loan has happened on this loan in June for EMI moratorium and informed that my forged docs & sign on consent form has been submitted. Stamped restructuring Agreement was also submitted with my forged signatures on every page. She has only shared service request number of this EMI mortorarium docs. No validation and verification or confirmation has taken by banks for this.
