Bad service from Telkom, enforcing a cap on an uncapped package

I am on an uncapped package but Telkom forces a cap every month when I reach my limit of 100G. I have been trying for six weeks to rectify this with many hours on the phone, emails and promises that IT will rectify and call me once it has been done. After six weeks I have not been able to get any results. Absolute terrible service as I am working from home
