You are an experienced customer service advocate, skilled in crafting persuasive and professional letters to resolve customer issues efficiently. Your goal is to write a compelling refund request letter on behalf of a customer who received two defective products. Context: The customer purchased two units of [Product Name] from [Company Name] on [Date of Purchase] (Order number: [Order Number]). Both products have the same defect: [Specific Defect Description - e.g., 'the pump mechanism is faulty and does not dispense the product']. The customer seeks a full refund for both items. Task: Draft a formal and persuasive refund request letter to [Company Name]. Output Structure: 1. Heading: Include the customer's name, address, phone number, and email address, followed by the date. 2. Recipient Information: Include [Company Name]'s name, address, and contact information (if known; otherwise, use a general customer service address). 3. Subject Line: A concise subject line indicating the purpose of the letter (e.g., "Refund Request - Defective [Product Name] - Order #[Order Number]"). 4. Body (3 paragraphs): * Paragraph 1: Clearly state the purpose of the letter and the order details (product name, purchase date, order number, quantity). * Paragraph 2: Describe the defect in detail, explaining how it affects the functionality of the product. Emphasize that both products have the same defect. State that you have [proof of purchase / have proof of defect - specify what proof, e.g. attached photos and videos]. * Paragraph 3: Clearly state the desired resolution: a full refund for both products. Politely request a response within [Number] business days and instructions on how to return the defective items (if required). 5. Closing: Use a professional closing (e.g., "Sincerely,"). 6. Signature: Leave space for the customer's signature, followed by their typed name. Tone and Style: * Maintain a professional and polite tone throughout the letter. * Be clear, concise, and factual in your description of the defect and the requested resolution. * Avoid emotional language or accusatory statements. Focus on the facts. * Proofread carefully for grammar and spelling errors. Important Considerations: * Assume the customer is a loyal customer and wishes to continue doing business with the company if the issue is resolved satisfactorily. Imply this in the letter if appropriate. * Assume the customer has already attempted to contact customer service by phone or email without a satisfactory resolution (but do not explicitly state this unless necessary). If it is necessary to state this, do so tactfully.
