用英文编写催款留言发送给Nina

Dear Nina,

I hope this message finds you well. I am writing to follow up on the outstanding payment we have yet to receive from your end. As you are aware, the payment was due on the 15th of last month, and we have been waiting for it ever since.

I understand that unforeseen circumstances may have caused a delay in the payment process, but we kindly request that you settle the outstanding amount as soon as possible. Your prompt attention to this matter would be greatly appreciated.

Please let us know when we can expect the payment to be made, and if there are any issues that we can assist you with in the meantime. We value our business relationship with you and look forward to your timely response.

Thank you for your understanding and cooperation.

Best regards,

[Your Name]
