Itemised Billing Statements

Vodacom refuses to provide me with an itemised billing statement from 1 Nov to date. This option was also always available on their old website but it is no longer. My husband's data bill is absurdly high and vodacom can't give me an answer for this either. How do I now monitor the data usage? I will again get a R500/600 data bill and that excludes call fees and the supscription fees I have to pay. I will never do business with vodacom ever again.
