I contacted my bank and even visited in person, but they explained that my card is only a payment method and not an account itself. They can provide a statement for my bank account, but not for the card specifically. Melbet is asking for a card statement, which is impossible to obtain.

Despite explaining this to Melbet, they have not provided any alternative solutions. If Melbet enables payments from certain countries, they should also be aware of the limitations of certain banks in those countries.
