英语翻译很抱歉,由于我们只看了订单上的交期,忽略了您邮件的要求,误以为货物在27号才要发出,因此直到现在,货物还没有完成

My apologies. This is because we only noted the date stated on the order form and overlooked the request in the mail, so we mistakenly arranged the goods to be delivered on the 27th. Therefore the production of the goods are still in progress and are expected to be delivered on the 20th. I should be grateful if you would confirm and co-ordinate accordingly, thank you very much.
