Vodacom ******* charges and downgrade policies unfounded

Vodacom downgraded my fibre again (like every month) to 2mbps from 10mbps. They claim that I used 500GB on my uncapped fibre but can not provide me with the log files. I also do not have access to the router to check.

I want to cancel my service due to poor service and product value. I can get a better deal elsewhere with access to my router 247. ICASA ruled that Vodacom needed to give me access and Vodacom said they will but once the case was closed, they are silent. Vodacom is not adhering to the Consumer Protection Act and wants me to pay up the full contract. This is ******* and I will be reporting them to ICASA and the Consumer Tribunal. How many other clients were fooled by paying up in full?
