Vodacom "Hacked" but they say My service has been "suspended (sic)

0 out of 10! I am sitting working remotely no where near a landline and I try to make a call and my phone diverts me to a "Voice Message" that says my service has been suspended! Apparently (I he ar from three other people via e-mail) that hacking has taken place. What drives me insane is this: they do not send out an sms and why do they post voicemail that saya "your voicemail" has been suspended when they are being hacked. What direct Vodacom call number can I call to establish what is going on?
