Continuous suspension of cellphone line

Vodacom has for the past couple of months continued to suspend my BUSINESS line every month almost a month after payment has been made. last month i was told my line was suspended because THEIR SYSTEM HADNT UPDATED AND REFLECTED MY PAYMENT. As I am writing this report i am on the line with a very helpful gent who is also confirming that he has no idea why the line is suspended as it shows on the system that it is up to date with no arrears amount. MEANWHILE IM LOSING OUT ON BUSINESS CALLS.
