My VIVOBOOK X515JAB_A516JA only came with 28 GB of space, what's wrong?

@Void_asus
Could you please open the laptop to the storage device page so that I can confirm the size of your storage space?
Additionally, I have messaged you, please provide your laptop's serial number through the message so that I can confirm its shipping specifications. 
Thank you.
