Need some help. A couple of months ago me and a friend finished building a site for his dad. We didnt get paid yet but I was promised that we would. Me and my friend got in to a fight and after a few months he put the site up without my consent. I did over 90% of the site but obviously dont have any proof of it. It is a Joomla based site.
I've even emailed his dad but got no response from him. Do you have any tips for me?
