Telkom let alone any of the other broadband company should be allowed to do their own testing, an independent company should run these and publish them to avoid this kind of thing!. Infact, several companies should run these more regularly and post them somewhere on a monthly bases!
Ofcourse Telkom would lie, they're known to do this. - No surprise.
It definitely wasn't an innocent mistake!! They modified the Feb. stats after it got noticed. They're trying to fool us....or Telkom can travel back in time........
