Донесите до меня смысл, пожалуйста

Заказала платья к концерту. Теперь жду и нервничаю. Вот что написал продавец:

"Dear, your order is too heavy, I have 3 packages. But I saw 2 with logistics information and the other without. Then I found out that there are still several other parcels with no logistics information, and the post office is still in the process of investigation. In order to avoid delaying your time, our store decided to send you a package again, TRACK NUMBER is the same as before. I am very sorry, because the double 11 event, the parcel over there is full of packages, such things happen, we do not want to see, I hope you can understand and support. Thank you
