Bad Customer Service

I renewed my Vodacom Data contract in March 2020 just after outbreak of COVID as I had to work from home. A year later their network was very bad during the day and I was forced to work very late in the evening when lots of users were asleep. My son was also not able to attend online classes. I phoned Vodacom to complain and they asked about my address and referred my query to the network team. A network team member confirmed that there were many subscribers in my area for Vodacom 's infrastructure to service them. The agreement was she would write a note to the relevant department so they could terminate my contract since i was not getting the service i was paying for. But she disappeared. I was debited for the whole year without receiving service. In April 2022 i called to check the status of my contract and they confirmed it expired so i cancelled my debit order. Now it seems that Vodacom 's system renewed my contract in error and i am referred to the legal department for not paying. I have spoken to many consultants in the last 4 months and it seems they don't how to resolve the issue. I hope to get someone senior in Vodacom to resolve this matter
