I can't check the delivery, but is it impossible to check the delivery?

We are very sorry for the late response.
The delivered invoice number is automatically sent by KakaoTalk or text message on your mobile phone when it is sent. Have you ever received it?
It appears that you have already received it well after the period has passed, but if you feel uncomfortable, I apologize again.
Arttystation will always do its best.
Thank you ^^
