问题: 请帮助我翻译成英文（一个邮件）
先生 你好 我已经是第5次给你发送电邮了，我们向爱尔兰发的单据已经由银行寄出20天了，可我们仍没有收到货款。先前客户已经承诺接受不符点单据，请您联系客户，尽快给我们付款。非常感谢！
解答:
Hope you are well, Sir. This is my 5th message via e-mail to you. Our invoice and all payment related documents to Ireland were being mailed off by our bank 20 days ago. However, we have not been able to receive any remittance so far. As you will recall, the customer has previously promised to accept unmatched documents. It would be much appreciated if you could contact the customer directly and effect payment the earliest at your convenience. Much obliged.
not quite sure the meaning of : 不符点单据
