Translate the following information into Chinese D...

Translate the following information into Chinese Dear Pon, Order No. XE23003 The order mentioned above was delivered to us on September 4, 2010. It is with great regret we have to complain about the packing of Bale 4 and the quality of the material in Bale 2. Bale 4 does not appear to have packed in waterproof material and has become very sodden on arrival. As a result, the 500 meters of your material AC303 it contained has been very badly stained and show signs of rotting. The material in Bale 2, 750 meters of AC223, is not up to the standard of the similar material we ordered from you on May 4, 2010. It appears to be too loosely woven and pulls out of shape very easily. Under separate cover by air parcel post we have sent you a cutting of this material and also one from the material we obtained from you on your previous visit to us. You will be able to compare the two for yourselves. We have always been able to rely on the high quality of your materials and packing in the past. We are, however, disappointed on this occasion as we have received orders which need these materials for production. We will, therefore, appreciate it if you can let us know without delay what action you can take to help us to get over present difficulty. I look forward to your prompt reply. Yours faithfully,
