Telemarketer threatened to rape me?

I received a call from a scam. I called it out as such, stating that it is illegal for those wishing to do business in my country to say they have a prior business relationship with you when they do not. He immediately began swearing and calling me dirty names; I told him this does not bode well for convincing me of the legality of the operation if he is so unprofessional. He kept telling me to hang up, so I questioned him if he had this ability, or if I could stay on the line and prevent him from scamming someone else.

He then read my address to me and said he was going to come here and rape me. I flatly told him that what he said was a threat and he had just broken another law by threatening me. He further called me demeaning, dirty names. I asked him who he was, where he was calling from, etc. He asked me why, I said if he was legal, he would know the law required him to give me answers. He evaded and eventually hung up.

I immediately called the police, thinking I would just report the stat, but they said threats of bodily harm required the presence of an officer so they would send one to my home. I felt embarrassed, and said I didn't feel right about taking on officer of the street for a petty little boy trying to be big. I agreed to come in for an appointment to file tomorrow.

What kind of person thinks it is okay to say such a thing, and especially when called on it? The more I sit with this, the more uneasy I feel. I am getting scared. Help!
