Vox Unable to fix Uncapped package running out of data since

Vox Unable to fix Uncapped package running out of data since the 18th of August 2019. My husband and I have had numerous telephonic calls to sort this out but unfortunately had no luck in getting it fixed. We are currently subscribed to your NeoBroadband Wireless Uncapped, via Neotel/Liquid Telecom. The NewBroadband connection was replaced with a LTE Router with an MTN simcard. Now every second week we run out of data, and the data provided is less than 10GB. However i'm paying for Uncapped. I'm "out of data" since the 2nd of October. With numerous different technicians calling, but they are not able to fix/resolve this issue. I want my uncapped to be restored, or please cancel my account, with no chargers out of this contract. Since Vox can no longer provide me with the service I'm contracted with. Acc No. *** VOX***6 VOX***4 VOX***1 VOX***7
