Vodacom unable to load data bundles on my account

So vodacom, you guys thought you were brilliant in migrating me to the new cd3 or whatever its called accounting system. When you did that, i was unable to purchase any data bundles for. You then have the audacity to charge me out of data bundle rates. I called onto your call centre in December, the agent qas unable to laod a data bundle on my behalf as well. I raised my concern that this is unacceptable amd frankly **************** that i have to pay for out of bundle charges when you guys cannot top me up. Please reverse all my out of bundle charges immediately from my December statement. I'm not interested in an explanation as its *******. It was not a fault ony side that bundles could not be loaded but on your side. I have placed a stop on my account for the debit order until confirmation that the usage has been credited to my account.
