I was looking for Home loan self few years back and contacted an agent to help me out. He took all of documents as he said will apply in all banks. Post few years i found i am home loan gurantor for home loan to unknown person. This loan was taken by Jeetu Chanchalani who is unknown to me. I was unaware that i will be guarantor for this home loan while signing few docs via that agent at one branch. Somehow i managed to contact Mr. Jeetu and requested him to get my name removed and he agreed. Later on he sent request email to bank for removal of my name, but no action was taken. My cibil score is having big impact due to this laon and facing lot of issues getting any financial aid from reputed institution. I submitted request in Standard Public Grievance Redressal System of Vijaya Bank and got positive response as below Requested On : 10/5/2017 6:41:32 AM Response : Had a word with the customer, he is ready to change the guarantor at the earliest.
