No no. And I usually stay out of these things because the argument is pointless. If you have an uncapped service, that means uncapped.
Not "Uncapped unless you hit 250gb" or "Uncapped unless you don't visit telkom.co.za at least twice a month and stand on one leg singing the national anthem". Telkom is welcome to impose limits on their service but then they can't market it as uncapped.
It's a plain language thing.
If Telkom came into the open and said: "Ok, it's not really uncapped. We're giving you 300GB data a month. After that, you'll be throttled down to 4MB until you hit 350GB and then you'll be throttled down to 128k" people would have no basis for complaining. As it is, it's vague and stupid and a good way of pissing people off.
Disclaimer: I have three of these units. One is personal and used at home. Exclusively for streaming - it hits around 300GB a month so pretty light considering all the devices. Wasn't throttled. I have two at my school that are used for +- 100 staff and +- 1100 students so rack up about 3TB a month. These were also not throttled.
