This guy Andile Mngxitama / Myxomatosis is a dangerous cretin.

Quote "It is definitely not our number. We have a telkom line".

Andile, the SMS's were almost certainly sent via a cellphone, and you and your mob have plenty of those.
It is also possible to send an SMS via a PC and a telkom line, FYI

Andile, please provide even a shred of evidence that a white person did this - ANY.

Keep it up, Andile - one day you will cross the line and end up seeing your ass in civil court.
