Multichoice DSTV blown away by competition?

Multichoice, for long South Africa's only satellite TV provider, seems to have rolled over and died the moment competition appeared on the scene.

One can't get their broadcasts, one can't get them on the phone, and they don't respond to e-mails.

Have their competitors found a sophisticated way of jamming their broadcasts, their phone lines and their e-mail all at once?

Does anyone know?
