Credit Rating over 800 - No contract allowed

I run a very successful business in existence for over 3 years and helping the youth of this great country. <br> <br> App**** for Vodacom contract using company and was told my personal credit rating was not suffcient!! The application is in the companies name and NOT mine!!! Anyway, I checked my credit score and it is free from any bad history, in fact I score 808 / 999 and am classified as very good credit risk... so *** are Vodacom on about??? I want to sue Vodacom for defamation..
