Do you need to Request of Arbitration to get back money back on order when developer left no files at all?

 
The developer seems to have vanished. Left no files to be reviewed so far, hoping he will reappear before time goes out but looks unlikely at the moment. Do I still need to do this  Request of Arbitration precedure to get back money or can I just cancel the order some quicker way? If developer doesn't deliver I've lost some time on this so would be great to be able to be able to re apply the order as quick as possible.
