I can only say that my limited experience of Web-Mania has been very, very good. They processed eveyrthing and had my site live within 24 hours and nothing has gone wrong with it since.
Have you tried the Live Help link on their support page ?
It opens up a chat applet and allows you to bounce things around in real time with their support technicians. Obviously you shouldn't discuss actual details of financial issues via this method, but I've just asked on of the techs on your behalf and he/she assured me that if you have an invoice number you can quote to them using the Live Help system they will be able to check on the status of your account in real time and inform you of what is going on.
Post back once you've been in touch with them with the results.
They were very friendly and helpful when I asked on your behalf, so I expect nothing less if you go to them direct.
