No Service on Broadband

I have the 200gb broadband a month that I pay over a thousand rand a month for... And the past three weeks I get no service... I know this product can work as the first month I had it, it worked perfectly fine... Yes Telkom I have rebooted, yes Telkom I have resetted, yes Telkom I have sim swopped, yes Telkom the router is fine, yes Telkom my area is covered and yes Telkom I have full signal! I can't stream, I can't download, I can't even load a Web page on my phone... I do not even get 1mbps, my upload is amazing... Yet I get no download speed and my latency jumps over the 2000's! What kind of **** service is this that I have to pay over a thousand rand a month for? In the same location with Vodacom I get 15mbps and no latency, on 2 BARS OF SIGNAL! 2 BARS OF SIGNAL! Yet with full signal on Telkom I get 120kbps...i want this resolved... Or I want my contract cancelled so I can move to a service provider that grants me what I actually pay for and what they advertise.
