A refund is the process of returning money to a customer who is dissatisfied with a product or service. This can happen for various reasons, such as receiving a defective item, not meeting expectations, or canceling a service. Refunds are typically issued by businesses to maintain customer satisfaction and loyalty. To request a refund, customers usually need to provide proof of purchase, such as a receipt. Many companies have specific policies regarding refunds, including time limits and conditions for eligibility. Understanding these policies can help customers navigate the refund process more effectively and ensure they receive their money back when warranted.
