Hdfc Bank And Vertax Radi Go Car Dealer - Threat call and torture

I was in contact with credit card from last * years and I told them that my financial status is not good as I lost my job. Despite knowing this credit card people are calling my relatives in India and outside and using abusive language. They called me and gave me threat calls that if I will not pay money then they will disclose this to all. He also told me that they have my marriage pictures and they can use it anywhere.
