Solicitor called ( location indicated Big Bear, CA), selling vacation packages involving the Hilton. I answered, thinking it might be an acquaintance from there. When I indicated that I wasn't interested and asked to be taken off his call list, I was rudely told "that's not how it works, lady, it's automated calling and you answered and I can call you as much as I want" then promptly hung up on me. Disrespectful little punk.
Let him call you back, but hack him off by completely ignoring his and any unknown numbers. That's how you really waste their time, not by tying them up calling back. You get a telepest that's getting nothing from the numbers they call, it makes for an awful day. Don't get into discussions with these con artists and certainly don't waste time telling them to remove you from their lists, it often brings out absurd and belligerent behavior.
Call was blocked by a great app I have. But there was a voicemail. after a few seconds of silence there was a womans voice having a conversation. She stated a name or two the most clear was Yani? Many things were said including very foul language/explatives. Saving that voicemail in case I get harassed by this number again. Already sent the voicemail to my email as well as a couple of attorney friends to see what they have to say about it.
