Discovering unauthorized charges on your account can be alarming, but Contoso has a straightforward process for disputing these transactions. If you notice a charge that you did not authorize, the first step is to gather all relevant information, including the transaction date, amount, and merchant name. You can then contact Contoso's customer service via phone or our online messaging system to report the issue. It’s essential to notify us as soon as possible, as prompt reporting can increase the chances of a successful dispute. During the call, a representative will guide you through the dispute process and may require you to complete a dispute form. Contoso will investigate the disputed transaction, which may involve contacting the merchant for additional information. You will receive updates throughout the investigation, and if the dispute is resolved in your favor, the unauthorized charge will be refunded to your account. For added security, regularly monitor your account transactions and set up alerts to notify you of any unusual activity. If you have further questions about disputes, our customer service team is here to help.
