To dispute a Mastercard Debit card transaction:

  1. Attempt to contact the merchant. You MUST have made contact with the merchant in effort to resolve the dispute, PRIOR to submitting a letter to BayPort CU. If contact has been made with no resolution or there is no means of contact, you must complete a "Mastercard Debit Dispute Form".
