Starting a paid hosting account isn't something you need to open a ticket for. Just click the link above that says "Free web hosting & domains". It is not only for the free accounts.
I now that... but the site takes me through the whole process... but at the page where I am suposed to pay... there is no possibility to pay.
It shows how much I have to pay and a line that says something about: this site cannot help you any further.
And that is it.
Well, if there is a general problem at Bravenet that prevents everyone from paying I think they will have noticed and made fixing it their no 1 priority.
I would also have expected a lot more messages from people in your situation.
The alternate explanation is that there is a problem on your end. Easiest thing to try is doing it again in another browser.
