I think your anger is a bit misplaced given that from reading of your case it appears that all the trouble you've had is a bit self inflicted.
Your complaint, if I can understand correctly, is that you've hired a developer to build a website, for which you've paid 75% already - and run into trouble on the last 25%, for which the developer has returned your money.
First of all - we make this abundantly clear on the site - you should never, ever pay funds unless the deliverables are complete and you are 100% happy. This is the real world, and just like eBay there are good, average and not so good people participating in the marketplace. Luckily, we provide protective mechanisms like our Milestone Payment system which works a bit like escrow. If you use it properly you will always get all your money back if something goes wrong. If, however, you make payments in advance of finished product then you are really assuming the risk here.
Secondly - NovaStudios has 406 feedbacks, and from their profile it looks like they have a degree from Harvard and come from Cleveland, Ohio. Having run Freelancer for 4 years I can say for certain that you don't get that far on the site being a bad developer and if I could hazard a guess I would say the relationship broke down more than anything.
Thirdly - you are wrong about your 2nd lesson. The system is not prone to abuse if you follow the guidelines. You are also free at any time to file an "incomplete" report which is an extremely negative review if you think it is justified.
Finally, I may add, the first I heard of this issue was an abusive email from you at 6am this morning. It's 7am now. Given you had my personal email address I would have been more than happy to look into this but instead you went off and posted this here without giving me a chance to look at your case. If you expect customer service, at least give someone the chance to deliver it.
