pls help to transfer to englis

所有送貨單已蓋上客戶印章,如未能清楚看見請通知
All the Delivery Note have been chop, if you can't see clearly, pls call us. Thanks.
Nothing's wrong with it. But i'll write it this way:

All the delivery notes were stamped, please notify us if
they are not clear enough to see. Thank you.

Thanks.

基本表達到。只是delivery notes要眾數和have been chopped是past participle，並且see後面要表明不能看見甚麼(object)才是正確文法。

All the Delivery Notes have been chopped, if you can't see them clearly, pls call us. Thanks.

另外可香港人才明chop這東西，外國人會用stamped來理解蓋印這東西。這是給你參考，並不是句子錯對的問題。
