Failing to provide services adequately. I am ready to cancel!😡

It's been 3 weeks and my wifi is still not working. I have classes everyday that I need to attend virtually and that has forced me to buy data. Firstly, the call center has been nothing but helpful. They are great BUT the TECHNICAL TEAM is Horrible. They promise to call but never call or call to provide excuses. They have **** so many time and I only found this out last week Thursday when the call center lady asked me if they can come on a Saturday, this shocked me because the technical guy from the first week kept on telling me that they do not work on weekends. Furthermore, the technical team lies in the reference number and say I keep on changing my appointments! Now tell me how I manage to change an appointment that was never communicated to me. And whenever I ask whether they can come after 16h00 because I work during the day, they all give me excuses of having to be at centurion and promise to call me back but never do so I end up calling them and they give me more excuses. I'm so over VODACOM because the fail to provide me with services I pay for and yet I am the one who must constantly call back and create new tracking numbers everytime for your failure. What makes it worse is that Vodacom is very quick to take my money first thing in the early money and I bet you it will take months for me to get credited for the three weeks. I'm so disappointed and even more ready to cancel and leave Vodacom completely
