No internet for 5 months and Telkom not willing to assist but charging the client *****ulently

We have Telkom Fibre connected from last year after switching from the ADSL line. However, there has been a fault with the fibre connection since last year. We called multiple times to get assistance to troubleshoot the issue with consultants on the helpline INSISTING it is the router. As requested, we took the router to the store for testing and it was in working order. The cables are not faulty either, we checked. We obviously needed the issue resolved because how can a paying customer pay for internet services for 5 months to not have internet access at all!! The line is completely dead and you are unable to connect any device to it. When we called the call centre to assist further, it seems like no one knows what they’re doing or how to advise. They are reluctant to send a technician and threatening that we can to cover the cost of the technician it fix a fault that is not on our end!!! Get your **** together! You are a service provider. It is literally your business to provide a service. Why are you not troubleshooting and fixing the issue?! Telkom is being *****ulent by asking the customer to cover the cost of a fault on their side and still charging the client every month since November last year when there has been no internet access up until now March 2024. I want a report run from the time the fibre was installed until now stating which months the internet actually worked for!!! And I want a full refund for the months it was not operational!!! In December, we all arrived home and some of us had to work. I had to hotspot my phone for a week due to negligence, zero assistance and absolutely no internet connection from Telkom. You are absolutely pathetic. Please get me in touch with a consultant so we can be refunded for your pathetic services and terminate the contract based on you breaching it.
