Hope that you have got your account set up to your satisfaction by now. I can understand what you are saying about being "slick" but I know I would definitely prefer it to work and be a little ugly in places than "slick" and "pretty" but be a complete disaster working wise or even worse be a con!
In my experience, sites that are very "slick" and pretty are mainly cons or look pretty but don't work. Most genuine systems normally have a few rough edges. I would assume that if you have got the "Thank you for ordering from eUKhost" message that your sale has completed successfully. Also, as Jonathan mentioned you should get an e-mail confirming this also.
Also if you paid by Paypal you should also get sales confirmation from the by both e-mail and on your account
