Mountnman, usually the keys come attached to an email with instructions. Did you get/follow these? If you didn't process not complete the transaction will need to clear. If you got this,in what way are they not working, maybe you need to re-downloadkeys & try again.
BTW the process of notification is initially automated. As is payment so it will take upto a couple of days(this seems to depend on your bank etc). You should recieve a email notification of reciept of your quiery. But an answer will take longer.
No they're not cowboys, you'll get there. Of course being a bank holiday won't help.
P.S.If you've got the emails, but can't download keys. It may be your firewall. Check settings, you have have to change these.
