Forced payments without service

I have been a paying customer of Vodacom since ~ 1998. On 15 February 2015 I requested a transfer of my personal mobile account to my business. This was also on my upgrade anniversary. My upgrade was processed to the business rates, but the account was never transferred. The Vodacom shop lost my application and neither the normal or business call centre were able to help me. I since went back to the store on the 16th April, refilled all the forms and provided all the documentation. There has since been no feedback or resolution of the matter. I continue to send daily e-mails and call the store, with no response. I have to continue paying the bill or cancel and pay 70% of the balance of contract for a service they cannot provide. This is an abuse of consumers by mighty corporates.
