I recently found out I got tangled into some sort of scam which I wrote about it this question.
The other mysterious bit of it is that the scammers were able to hold on to my new card details even though the old card details takeover had taken place way before I applied for a new card.
Just to clarify, the cards are in the same bank and have the same number but different expiration dates.
The question is, how the scammers (or retailers in other cases) are able to update card details automatically without me knowing about it?
