Language option almost NEVER available

Sometimes, like today, I have to make a call to the call centre to discuss something technical which is difficult to explain in English. Therefore I prefer the Afrikaans option, but it is almost never possible to get someone to speak Afrikaans. I know that the Afrikaans agents may be busy, but why not appoint more people who can speak Afrikaans? In 95% of cases I am put through to an English agent although I chose the Afrikaans option.
