Vodacom needs a new provider for credit checks

I tried to apply for a new contract as I cancelled my contract may years ago with Vodacom and remained on a pay as you go basis. I received one text message saying it has been declined with no indication as to why. Vodacom customer care cannot assist me and says I have to call Experian myself but their provider "Experian" doesn't answer their phones to clear up this matter. I have a near perfect credit score and cannot understand which idiot didn't do their job properly. To add to my frustration on not getting an answer as to why I was declined I attempted to reapply, and the Vodacom customer care informed me I cannot reapply for 60 days. I also cannot understand why Vodacom cannot assist - don't you want my business?
