Vodacom force a client to pay for nonexsisting account

I had a dispute with Vodacom regarding ***** occurred in my bank account in their name in 2018. After failing many times to get them resolve my problem, I decided to settle all amount I owed them and requested that thy close my accounts since I was disconnected from their network for more than 5 months. It was in November 2018 when talking to their consultant telephonically that I requested the contract be closed since in the stores they told me I have to cancel or close any contract telephonically. In 2019 July I stated getting new notices from Vodacom saying they reinstated my account and billed me so I must pay. Even today they still bill me for nothing and want me to pay for service I don't use, contract I asked them to close in 2018. I want VVM and MDB to remove my name from blacklisting as they are after me saying there is nothing they can do but to force me to pay as instructed by Vodacom. Can please Hellopeter help me to get Vodacom off my back.
