A payment dispute occurs when a buyer and seller disagree over a transaction. This can happen for various reasons, such as receiving a faulty product, unauthorized charges, or failure to deliver goods or services as promised. Both parties may need to provide evidence to support their claims, which can include receipts, emails, or photographs. To resolve a payment dispute, individuals often turn to their financial institutions or payment processors, such as PayPal or credit card companies. These organizations typically have procedures in place to investigate the issue and mediate between the parties involved, aiming to reach a fair resolution.
