商务英语写作范文:询问装运

Dear Sirs,

　　Referring to our previous letters and e-mails,we wish to call your attention to the fact that up to the present moment，no news has come from you about the shipment under the captioned contract.

　　As you have been informed in one of our previous letters,the customers are in urgent need of the goods contracted and are in fact pressing us for assurance of timely delivery.

　　Under the circumstances,it is obviously impossible for us to again extend our L/C No.3059,which expires on August 21st,and we are obliged to remind you of this matter once again.

　　As your prompt attention to shipment is most desirable to all parties concerned,we hope you will let us have your shipping advice by telephone without fail.?　　

　　Yours faithfully，
