Convenience Is Not On The Cards

(I take payments from our customers. The following situation happens on a regular basis.)

Customer: *by email* “Please charge my invoice to my credit card on file.”

Me: *after trying the card, and it is declined* “Your credit card ending in 1234 was declined. If you would like to use another card, please call me with the number.”

Customer: “Oh, that card was compromised/had fraudulent charges on it, so I had to get a new one. The new card number is—” *gives entire card number, expiration date, security code, and billing address*

Me: *after deleting the credit card number* “Thank you for your new credit card number. In the future, please call me if you have a new credit card.”

Customer: “Why? Emailing it is so much faster.”

Me: *facepalm*
