Telkom caps uncapped internet

I have a uncapped lte contract with telkom. This month I got 2 new laptop's so my data usage was more then normal. As per fair usage I expected telkom to throttle me. I was happy with this. Instead telkom completely stopped my internet connection. When I called the call centre they explained to me that the fair usage policy is the reason why the connection was suspended. I tried to explain that the contract is for uncapped internet but was told that if I want to dispute the contract I must get a lawyer. I read the fair usage policy on the internet and it stated that the speed will be slowed down to 2mbs not cut. So when is uncapped capped when you have a contract with telkom apparently. My contract ends in June unfortunately then I will see maybe probably their competitors will offer me a better deal than 365 gigs for R800. Cell C
