A gentleman with an Indian accent called my home to talk about solar energy, and when I said I wasn't interested, he chuckled and asked what I was not interested in b/c it was not a sales call. I told him I wasn't interested in speaking with him. He said I had no right to tell him that. I insisted that I did, because he called me and interrupted my day. He chuckled again and asked if I tell my relatives that I wasn't interested in speaking with them when they call. I informed him that he is NOT my relative. He laughed and said he could be. I asked him to remove my name and number from his list and not call again, to which he laughed and hung up.
You could tell them their number, & any other one they use, will now be automatically entered into the Neighborhood Report, which lists phone numbers of sexual assault creeps & pedophiles. Doubt he'd ever call you another name or try to make another call to you again. Also call your state's consumer affairs office & tell them what he said. So his threat of 100 calls will go nowhere at all.
