[Resolved]  HDFC Bank — harassment by credit card department

I had hdfc credit card 3 years back, but after sometime lost my job so my card was used by my one of a relative. He made a purchase of 30000 without my knowledge and said that he will pay the amount to bank on monthly basis.
Once he delayed few payments i called bank and asked them to block my card and they did so. But since past few days different different people are calling my family, friends and they are harassing my friends and family. Is this the kind of service you guys are providing. However after many calls i asked my relative to pay the amount so i same told to the person who called me but he is abusive over call and is not ready for settlement. My card ends with 5266.
I want this to be settled for once and final. And please hier people who can talk to others properly, feels like they use to abuse their mothers and fathers in their houses.
