Incorrect billing

For the last couple of months, vodacom has been over charging me and under delivering. They have basically billed me for in un-capped data while forcing me to make do with a 100gig bundle.

This whole saga stretches back to November 2018. First they refused to suspend my fibre while I was in the process of moving. Which means I was billed for an unused facility for two months. I moved into a new unit in Jan, and the agreement with them was that an interim solution would be provided since there wasn't any fibre infrastructure in the area. This was to be billed at a lower price than my regular facility which I am contracted for.

It's two months of trying to sort this out while being **** to by their call center agents. Now it has finally culminated in this scenario where I am without a connection and my business is suffering. Someone please help.
