Why my item(Business card AI and EPS FILE) has been rejected at graphicriver by quality team reviewer?

I receive a message from them and it says :

Thank you for your submission. We have completed our review of “Corporate Business Card - Rounded and Ractangle” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.

Here is the link to the files : https://www.dropbox.com/sh/f2wt8kdoq3umhjs/AAAhavTnC8Hhw8_Tj1t0Jg6ga?dl=0

Can anyone help me?
