Bad customer service VUMA REACH

I'm done wrong by VIMA REACH I paid for reconnection to VUMA last Sunday and it's Sunday today no internet access. I was called by their agent by the name of Anele I gave her all the information she needed and I waited for the reconnection nothing happened. I called their landline number and I got the voicemail that said I should leave the message which I did but still nothing. I texted their sales agent by the name of Nhlakanipho and gave him my frustration he promised to get me that password. When he did comeback I texted him again and he gave me the WhatsApp number to text, I did that then the robot asked for my details which I shared and it said I'm being redirected to the agent that was Friday. No agent called and on Saturday I texted again the same drill and up until now no call from an agent and no internet access. Now I demand for my internet connection or my R399 to be refunded immediately so that I look for another service provider. This is the second time VUMA does this to me and now I'm fed up with thier poor service.
