拜托 哪位高人帮我翻译一下吧 外贸函电的 ？？谢谢了 急呀

Dear sirs,
We have received your L/C which was opened by chartered bank lately. Through the carefully checking, we found that there are some discrepancies with our sales contract. The discrepancies are as follows:
1. We have agreed the trade term should be “CFR” not “FOB”.
2. It should be allowed to transshipment and partial shipment .
3. It should add “about” in front of the quantity.
Please amend the L/C and the shipment date and the validity of the L/C to the end of September and extends respectively October 15 th. Thank you for your cooperation.\
Yours sincerely

尊敬するXX先生　　　殿
　贵社は　Chartered银行にて　开设されていただきましたL/Cが　拝见致しました　详しく审査して
L/Cの条项には　契约书との条款に　合わない所があります　辻褄が合わないことは　次のとおり
1．弊社　出荷する価额は　CFRとすることで　「FOBでは　なく」
2．バッチ出荷と　トランシップメントが　许可できること
3．数量の前に　「约」と云う字が　付けてください　「ブラス　　マイナスに　说明す」
　つきましては　L/Cの出港日及び有効期限を延ばして9月末と十月十五日まで　直して下さいませ
　御协力　感谢しております
