"It serves them right if they think their credit card company will ask for those numerous details over the phone, or be it email."

Um, Leon, I don't know how to tell this, but the credit card companies *DO* ask you for those details over the phone. Maybe not all the time, but if they suspect the card is stolen, they *WILL* ask you for personal details and the credit card number and CVV/CVC to confirm that you are the account holder and that you are in physical possession of the card. At least (some of) the credit card companies here in the US do that (Citi and Bank of America).
