Negative credit rating due to Vodacom error

<p>Been trying to upgrade for a week now to find out I have a negative on my credit rating of R89 to Vodacom which I made payment for only to find out from Vodacom Accounts that this amount does not exist!!! Still can't upgrade and problem taking forever to be resolved!</p> <p> </p> <p>Been on the phone everyday to Accounts and Customer Service and every individual i speak to gives me a different story.</p> <p> </p> <p>Vodacom made the error - why is it not fixed yet!!!!</p>
