英语翻译我们查找了很多遍,最终没有找到和你地址对应的快递单号,我们又认真核对了一遍,才发现地址寄错了,有一个客户的地址寄

Hello,客户名字 I have checked it out many times and got no status information for the track number we gave you before.Finally, We found out that we've made a big mistake, we sent your book to the wrong address(our another customer's address), what's more unfortunately, the book has been signed, so i don't think there's any possibility that it would be send back. I feel so sorry and guilty about that. I apologize to you about that. it's definitely our fault. You can open dispute and we will offer you full refund and additional 2 $ as personal compensation to you. This is the best we can do for you. I apologize again and hope it wont bother you too much.(给分,外贸的）
