I think what happens is that ‘Amazon’, or whoever the scammers are, seem to take over people’s phone numbers. Goodness knows how they do this, but this is why blocking numbers doesn’t work. I only know this because it happened to us. One morning I received a number of calls from worried people who I had supposedly just phoned and they were calling back, having missed my ‘call’. They were from all over the country, and I had several conversations with people assuring them that I hadn’t just phoned them. I soon realised what must have happened and that our number had been ‘spoofed’. We literally had a dozen calls within an hour. It was quite scary and I had no idea how to stop it. Eventually I had to leave the phone off the hook and the scammers must’ve moved on to using a different number, because an hour or so later it just stopped. Fortunately the calls were not charged to us but it was very concerning. I called the phone company but they said there was nothing they could do! It’s awful what tricks scammers use.
