two sites in two different countries

Okay, so we had a .co.uk site. We then launched a .co.za site, which
was a duplicate of the .co.uk site.

Like this we were listed on google.co.za - now we made changes to the
.co.za site so that it is not such a duplicate and we have vanished
from google.co.za.

Do you think we've been penalized or do you think we'll show up again?
