Just had 2 scam calls within 20 minutes

...at least presumably they were scams.

Both recorded, one supposedly from Amazon regarding my purchase of an iphone12 (which I haven’t made) U.K. accent.

2nd, American accent, supposedly from Visa, regarding a £600+ purchase I haven’t made.
I hung up on both.
We have checked online banking and there’s nothing.

For a moment I was in a tizz about ccs - I often keep a couple in a small purse I can slip in a pocket if I call in at a small local shop for e.g. bread towards the end of my usual walk. Couldn’t find the purse for a minute or two, but phew.
