Telkom Fiber upload speeds are not what it should be- Rigging or Throttling it by the ISP is possible

My Op[tic Fiber Home Network speed Upload is between 3 and 4 MBPS. Why Telkom SA? My download speed is more than 50MBPS what it should be. It is not even 5 MBPS on Upload. Telkom is rigging their speed Download. Best to cut over to Vodacom. Telkom SA is ****ming Customers' wrt MBPS Upload wrt Fiber. This is totally ridiculous. Or some Techie has made changes or updates not skilled checking and setting their Network Fiber Switches configurations correctly for their Customers. Or is the Telkom Router out of Date??? Will Telkom SA check the Router Configs and Software? Is the Software out of date? If so why do they not check on their software for their Routers and update it automatically. Such Deployment is reasonable.
