Where a Card Issuer discovers an internal error, or is informed of an error by a Cardholder making a complaint or a claim, then the Card Issuer should refund all other Cardholders who are affected by a similar error. The Card Issuer should issue a notice to all affected Cardholders, advising them of the error and the steps being taken for corrective action, including the amount of the refund to the Cardholders' accounts. This should be completed within 60 Calendar Days of the original error being identified.
