Unfair Treatment

I have a contract with Vodacom for fiber and I recently moved from Secunda to Fourways. In January I went to a Vodacom Shop to get assistance and they could not help me, they gave me a call center number. I called the call centre and requested that my Secunda contract be cancelled or moved to Fourways. They have not come back to me with a response to my request. The only person who assisted me is Cindy unfortunately she is also relying on another department for assistance. I sometimes work from home and I struggle with internet connection. I also have a 50 gig contract with them, which gave me problems for months and eventually started working recently. I have been paying for all these "services" and I have not been getting the service. Since they can't seem to help me, I request that they cancel all my data contracts with them and i will go somewhere else where I would be treated fairly.
