Credit Check Failure

Very poor service, I did an online application to add a contact to my existing ones. I was told after I did an follow up call that I didn't meet the vodacom credit check. After many calls trying to find out why I was told it was because of the credit beureu. I found out from the credit beureu if there is any problems there and I am way past in the green. I would love to know how you do your checks because very clearly they don't work!
