The Wrong Transaction Complaint Letter is a crucial document used when an incorrect financial transaction needs to be disputed with a financial institution in the Netherlands. This document is particularly relevant when bank transfers, direct debits, or card payments have been processed incorrectly, for the wrong amount, or to the wrong recipient. Operating within the framework of Dutch financial law, particularly the Financial Supervision Act (Wft) and the Dutch Civil Code, this letter serves as the initial formal step in the dispute resolution process. It should be used promptly after discovering a transaction error and must include specific details about the transaction, clear evidence of the error, and a formal request for correction. The document's format and content are designed to comply with Dutch financial regulations and consumer protection requirements, ensuring that the complaint is properly registered and processed by the receiving institution.
