Vodacom Business account

My Vodacom Business account was suspended without reason a week ago (12 August). The account is paid by debit order and never was in arrears. Since then, I have emailed and phoned the support lines several times, and have gotten nowhere. The newest excuse is that "Thando is not picking up her phone." Good stuff. On top of that, several of Vodacom's support people have now told me that I need to contact the account manager. This is Azeb, at Vodashop East Rand Mall, and since confirming on Friday last week that the account had been suspended and promising to follow up, she has not answered her phone at all. I don't see the point of having to work through an individual who may be on leave, sick, or simply napping at any point.
