I had a scammer the other day who asked about my motor accident which was not my fault. That's unbeliveable I said, how did you know I'd had an accident, it's only just happened, I'm still in the car waiting for the paramedics to arrive I said. She changed tack, and asked about any accidents I'd had in the past 50 years – well, it sounded like 50 years but could have been just 5. How did you know I'd been driving for over 50 years I asked, click, brrrrr…….
And another caller blocked. If I don't recognise a number I don't answer it and if the same or a very similar number comes up again, usually from a place where I know nobody or do business with nobody, then that gets blocked.
Senior management is only too keen to answer the phone even when it's a strange number, or call them back if they've rung off. I try and put her off doing that saying if they really want to talk to you they will call back. Let them pay for the call. If I do get a caller who gets through I decline from saying anything and just put the phone down "off the hook" for ten minutes or more.
What I do tell my family is, if a stranger phones and asks is that whoeversname they are calling, is that them, NOT to say yes, as they record that and the use that recording to claim that they authorised the purchase of whatever overpriced scam item they are flogging, which you will never receive anyway.
