Suspending lines despite desputed amounts

Early in last year (Jan) I logged a call through vodacom about an amount on my account for mobile data during a time when I wasn't using mobile data as I was making use of a free wifi connection. It was not and is still not resolved. Again in June I logged a further complaint for data used while we were asleep during the hours of 00:00 and 5:00am, we were forced to pay the amount for that disputed usage before lines would be reconnected(Both our phones hadand still has all possible automatic updates disabled), and the amount would be reversed once the call was resolved...to date no feedback has been given nor has it been resolved. In November again a new call was logged about data used when I wasn't in possesion of a data enabled phone as mine was in for repairs, documents were sent through and nothing happened that one was relogged in December as Vodacom claims they didnt receive it, it was logged and documents sent through again, vodacom still claim it wasnt received and they suspended my line again despite the disputes. In June we were up-to-date after the forced payment.
