Probably a scam, but nothing to do with Dave Hinde…
I expect it is scamsters who send a note purporting to be from a retailer which is somehow relevant to you, saying your card is declined.
I bet the email asks you to please click on this link to ‘our’ website in order to to re-enter your card details and CV2 number.
In some cases, the scamsters will get lucky and catch someone who has just ordered from the real site.
I bet if you check the real / full email address of the sender, it isn’t actually from Dave Hinde (or perfume shop or whoever).
Not sure how scamsters ‘know’ which retailers’ sites you have been to mind.
Maybe email is compromised. Or are the sites somehow hacked to capture real customer details?
Anyway, I wouldn’t click on the link to check!
