Frustrated for a year

I have had terrible service with Telkom since 2020. Terrible might be an understatement because I am expected to pay for a service that has been non existent for close to a year. My house WiFi stopped functioning and I reported, it took the technician two months to come to my place. Thinking my nightmares were over , I was wrong it was the beginning. The technician told me they could not replace the ****** cable outside my yard because it would be ****** again. Eversince no one has bothered but I am supposed to continue payments for a non existing service. From their side I am 100% sure they can see the WiFi has not been working for a year but still they should continue reaping from my torn pockets. I am both emotionally and physically drenched because of this. Frustrated!!
