IELTS blocking South Africans

IELTS written scores are almost always capped at 6.5 for South Africans. This was told to me by an examiner before the speaking section. In 2003 I scored a 9 for the written component. Now I'm capped at 6.5. I wrote the Toefl - almost full marks for all sections. IELTS is deliberately blocking South African test takers. Avoid.
