Dear K.Abbie
Thank you very much for your email. And we would like to say sorry and apologise for our mistake. This should not have happened and should have been rechecked before delivered.
Thank you again for your suggestion. We are having a meeting to seek the way to end this problem. We will inform you one more time soon about our action on this.
If you don't mind, we can send some of our people to help you sort out and clean the goods. If you are ok with this, we will go to your place today afternoon.
I have to say so sorry about this one more time.
