Appalling service and connectivity

I'm afraid to say that Vumatel's service is absolutely the worst. After endless emails and calling the call centre, they have still not responded. The actual problem is that I have been paying for a 50mbps line since Dec 2017. The maximum speed I have ever gotten is around 10mbps, sometimes even lower than 2mbps. This slow speed is consistent, no matter what time of the day. I have done all the usual steps asked of one - speed tests (but cannot use the speed test on the shop.vumatel.co.za website as no "speed test"button exists for me), connected my laptop directly to the ONT (on LAN cable) with no other devices connected to my network.

I can honestly say it's like a badly run government department, just seems to have no care in the world.
