Incompetence changing bundle

<p> I moved from 2mb business uncapped bundle to 4mb premium uncapped bundle at the end of April. Since then it to ages to get my adsl line upgraded. In May I was overcharged for my account and now again now again for June I get any invoice for R100 more than my bundle because of Afrihost errors.</p> <p>Why is my line at 10mb when I selected 4mb? I have requested this to be corrected, why isn't Afrihost able to do simple tasks? </p>
