When Frank Van Buren applied two credit cards to Exxon Mobil, two boxes with 1000 credit cards were delivered. Moreover, each card had a name and a card number, and it was supposed to be able to use properly. Buren says it will spend hours cutting and destroying all cards.

According to a spokesperson of Exxon Mobil, the cause is currently under investigation. Is it still a typo in the computer input?
