Perhaps the more appropriate place might be the South African government's Dept. of Trade and Industry (http://wwwdti.pwv.gov.za/dtiwww/). The Minister is Mr A. Erwin. His snail-mail address is:

Private Bag X274
Pretoria
0001
South Africa

He also has an email addess listed on the web site, but spamming him might be counter-productive. Does anybody from South Africa have a better person/place to email/write to? They should really be alerted to how bad this merger is for all of us.
