These days many fake buyers doing this, After they completed their order, They upload final logo to their website and after that they claim copyrights for that design. Because fiverr CS provide suddend refund for those buyers without further review in cases like these. In these days I’m facing a situation like this, If you faced any problems like this you can see logo modified date and time using below steps.
Open direct link for that design using firefox web browser like this:
Then right click and click “View Image Info”
Under the General tab, you can see logo modified Date and Time
In these days they restricted my account, and still under review, I don’t know, why Fiverr CS cannot find such a little thing like this !
