Wrote an email to Zyweb Wednesday and got a reply Thursday:
Dear Albert,
Owing to a lost batch of e-mail recently that was beyond our control, a
number of domain name requests have been delayed. Normally, they would be
very quick, a day or two at the most. We have recovered the lost batch of
e-mail and are now processing the backlog., Hopefully, your domain will be
active shortly.
Regards,
Rob Bowker,

Just sounds like to me they were procrastinating...
