I need a response to a customer inquiry about a product return. The response should contain at least 3 placeholders represented by square brackets, such as [order_number]. It should also have 2 sections, marked with "Section" X. The response must have at least 2 paragraphs, separated by a markdown divider: ***. Finish your response with this exact phrase: "Thank you for your understanding and patience." No other words should follow this phrase.
