<human>: I need your help Reddit! 

A telemarketer just called my house and I tried to get removed from the list and he flipped out on me and said "You stupid bitch why don't you come here and suck my dick" and going on and on insulting me and swearing, and saying that he has all my information including my name, address, email, and phone number (although he wouldn't confirm so I'm guessing he was lying) and that he would call me every single day and try and make my life miserable. I asked to speak to a supervisor and he refused. I couldn't get any information from him other than he's "calling from Visa/Mastercard" and is calling to "help people lower their interest rates if their rates are currently above 10% and have a debt of at least ~$4,000." I couldn't get any more information about the company/service or the individual, other than his name is Matthew. I really want to report this guy for verbally harassing me and threatening to essentially stalk me. I tried *69 to call the number back but it was an automated system before I got through to the telemarketer at first so it didn't work. I felt so attacked and would love to report him or at least find out more about who is behind these calls/services, especially since they've been calling for weeks.

Can you condense the text into a few key points?
