Hello
Myself Suraj Kumar. A loan of 8000 was taken on my name on behalf of lendbox.
The loan amount now sums upto 27000.
I am unaware of this loan as I have never used mobiwik or lendbox.
I have tried contacting the vompany several times but no one answers the call.
I have mailed too on which a senior associated didn't replied after a while.
This unknown loan is really affecting me cibil report.
If I do want to pay yhe loan amount too, I am not abe to do that as I don't know how to do that..
Please help.
