Just because it is an official account is not a reason to delay the receipt and evaluation.
The seller is not sure if the item has been received since there are no tidings from the other side, which makes the seller uneasy. After contacting the management twice, they said, "We have sent a request for evaluation of receipt, so please wait.
I have not heard anything from the other side at that time either.
I wish they would at least explain what the situation is.
