Phishing scam. Told the person I wasn't interested and they started hurling low-blow insults and telling me my mother should have aborted me when she had the chance. Classy.
That is horrible! Find a way to report them. I'm getting so fed up with telemarketing on my cell phone. I'm so sorry you were talked to that way. That person was a real sad sack.
Leonard ND on caller ID. Therefore I don't answer, just pickup receiver and hang right up! No time for these ridiculous waste of time telemarketer, robo calls, whatever!!!
