Poor service long term client

I app**** for a gold fusion account ,i requested that they transfer me from my cheque account but now i was told my application is declined due to credit bureau saying im not credit worthy yet?? how is this possible ? i been with FNB for 7 years till date and never missed a debit order or any sort of payment...

this is disgusting service ,telling me i should contact the credit bureua to see how i can manage my spending.How can my scores not match up when i check it shows green status ??
