Question

帮我翻译下这篇外贸函电，谢谢了~~

(1) Dear Sirs,

(Re: Your Order No.456 for Ammonium Sulphate)

With reference to our faxes dated the 20th of April and the 18th of May, requesting you to establish the L/C covering the above mentioned order, we regret having received no news from you up till now.

We wish to remind you that it was agreed, when placing the order, that you would establish the required L/C upon receipt of our Confirmation. Needless to say, we are placed in a very embarrassing situation now that one month has elapsed and nothing whatsoever has been heard from you. As the goods have been ready for shipment for quite some time, it behoves you to take immediate action, particularly since we cannot think of any valid reason for further delaying the opening of the credit.

Yours truly,

Answer 1

亲爱的先生，
（回复：关于硫酸铵PO号为456的订单）
依照四月20和五月18日的传真，要求你出具上面提到订单的LC，到目前为止我们还没收到新的消息。
我想提醒你，这个你是已经同意了，当下单的时候，你就应该开LC了给我们确认，不用说，我们现在的处境比较糟糕，一个月已经过去，但是我们上面也没有收到，货物已经好了，都要准备运输了，你应该立即采取行动，我们不想再要什么理由再延迟开信用证了。

真诚的你的
