Bajaj Finance — Harassment from Bajaj collection team

Baja has given an unsecured OD loan but due to covid effect I lost my job and not able to repay. Baja has NPA my loan and after that I am getting harassment, abusive and thretan calls on my and my wife's number.
Every day getting 30-40 calls with bad language and drinks puples, using very cheap and roadside language with my wife too.
Even they threads to kidnapp my wife and do very bad with her. She is so afraid to not going out from home and in depration, even she started think to finish herself.
I am not a will full defaulter and shared my problem to NFL many time, same has requested to collection team but I think they only want to finish our lives.

I don't know how bajaj will get there money by this if me or my wife has taken any harsh step against the life.
