You need to work on backend order processing and your "anti-fraud" system as it may be before working on design. No point in re-design if the system isn't working ha ha
We're very sorry you were rejected by our current system and therefore see it as flawed, but so far our methods have served us well. While we are working on new and more efficient methods of verification our current system has had 0 instances of charge back or fraud in a total of 5 months of trading. (3 months as QuickBitcoins). If you would like you can become a verified buyer with us. This will allow us to accept your order and you would also gain the ability to purchase more than $100 at a time, and for a much lower rate. If this seems like a good option to you please create an account on http://www.quickbitcoins.net
and upload the requested documentation. We'll take a look at it and see what we can work out.
