I need a response to a customer inquiry about a refund policy. The response should be professional and polite. <<Refund Policy Inquiry>>. The response must contain at least 3 placeholders represented by square brackets, such as [order number]. There should be 2 paragraphs. Paragraphs are separated with the markdown divider: ***. At the end of your response, please explicitly add a postscript starting with P.S. Include the keyword "appreciate" in the response. Finish your response with this exact phrase [ender]. No other words should follow this phrase. [ender] should be "Is there anything else I can help with?"
