Well, domains can take up to 72 hours to propogate on the net but it's usually much, much quicker than that.
When you purchased the domain I'm pretty sure you should have ( usually instantly ) got an email confirming the purchase and registration of the domain.
I'd suggest opening a support ticket up and getting in touch with EUK regards this issue.
