Terrible service and network

I am utterly disgusted with the service that I am getting from Rain, 2 days ago I logged a complaint (Request #***7) in regards to my network being slow. I received a reply from Tshepo. I requested a callback but none has called me. I just called their call center now still no help am being told there's nothing they can do I must wait for Tshepo to call me. I am very upset with this company, R500 is a lot of money to pay for a 5G network that is not working and you are told that there's nothing they can do. Not even a courtesy call to try to resolve the issue, let alone to try and dispatch a technician that can come and look at the problem. I am sitting with a router that is showing GREEN LIGHT let alone I cant even connect a cellphone, a mere cellphone. I need urgent assist or let me know if I should move to another service provider because you just don't care about your clients at all but you're faithful and committed when it goes to debiting the funds every month
