    • Note:
    In the case chargebacks, SIX and your financial institution are bound by the international regulations imposed by Mastercard and Visa, which means that they must comply with their formal requirements. Depending on the reason for disputing the transaction, this includes the obligation to provide evidence. Final clarification of this matter may, under certain circumstances, take some time, since various entities are involved. Please note that if documents are missing, this may lead to further delays.
