Canceled Completed Order !!!!

About 8 days ago, I got an order for a logo design.. He told me every thing about how he wanted his logo to look like... I designed a 4 versions and send him to choose. He said to give him some thing in 3d (beveled and with shadow)... I did. This time He asked me to do some revisions. After these revisions he said he liked the very first version that I send him. So he asked me to change some thing on this 1st version... I did
When every thing is done.

He simple said he wants to cancel the order because he is not getting what he wants...
Tell me
How can I cancel that order when I give a lot of time on it for 4$... He said he 'll go to customer support. after 2days customer support canceled that order and refunded the buyer... :(

Fiverr CS didn't even contact me or any thing else.
I request Customer Support to listen to both in future and then decide what to do....

Thanks
