Change account from Personal to Business

I have been trying for the past 3 months to get my Vodacom account moved to be paid by my business account. This business has been running successfully for the past 4 years. Until today this has not been done. After numerous calls and going to back to the Vodacom shop in Mall @ Reds several times, this matter has still not been resolved. Mweb took a week to make the same change. This is not acceptable
