Bad Service now disallowed upgrade

Following my trail of horrible experiences with Vodacom: My current account was blocked for 2 weeks of every month for 6 months because they kept on forgetting to remove the new account limit on my phone. I then said i refused to pay my account until they resolved the issue which they did not for 6 months. Now when I am about to upgrade I have found out that I was reported to the credit bureau over this period which now disallows me from upgrading my phone. Disgusted at the flippancy with which they treat a customers financial health.<br> <br> I am contactable via my email address.
