I had already written about the sale of an accident car and how the present owner is asking me 25%. He has been putting long threatening mails over the past 20 days. He is abusing me and my husband. He is using degrading words. He is threatening to put mails to family and friends, to organization, and all over the net. I have not replied to any mail until now. But day by day the words are becoming very abusive. Is there any way I can deal with this person ? Legally or threatening? If I go legally, what type of case can I put on him?
