Vodacom Changed something on my contracts

I've had 2 data contracts since end of May 2017, there was initially an issue with me not getting the data I was promised and the issue was sorted out for both contracts. That is up until the beginning of this month where things are definitely not right. For one thing is that the data allocated seems to much less and that I have no proper way of viewing my balances on these contracts: Vodacom App shows 0.00GB for both and Vodacom.co.za shows balances that I deem incorrect and "Monthly allocation : 6.04GB" which is far from what it should be.

I have skipped the whole call centre thing, because of past experiences with the clueless staff there.

I hope someone knowledgable can assit me with this issue as I am very dissapointed in this situation
