MTN VERY slow LTE internet speeds

Just ran a quick test of my LTE internet speed, mbps

Telkom Up Down Best: 13.3 3.54 Worst: 4.16 3.15

MTN Up Down Best: 5.39 1.09 Worst: 2.42 0.37

Who could ever believe that Telkom would thrash MTN?

When you go on the MTN Coverage map, they have massive Disclaimers all over the place. They do not give ANY indication of expected speed. I can quite understand why. How can one make an informed decision as to what to buy, if they give no information? They suck! Be warned!
