It’s horrifying what people will fall for.
I once had a wrong number phone call from a woman who sounded very elderly, with a quavery voice to match - who was terribly worried, because she’d had a call from Amazon to say she owed them money and if she didn’t ring such and such a number and pay now…..
By what stroke of sheer chance/luck she got me instead I don’t know - she told me she’d never ordered anything from amazon! So she’d fallen for it out of sheer fear and naïveté, poor thing.
Of course I was able to reassure her that it was a SCAM, made by heartless criminals, she had absolutely nothing to worry about, so please just forget it.
A very naive and trusting elderly neighbour of ours was scammed out of over £100k. I am quite sure such people are deliberately targeted - there are ways of identifying likely targets, and I’m pretty sure I know how our neighbour was chosen.
