they were reselling (?):
dsl go 25 (R1495.00) as DSLXtreme Lite uncapped (R1495.00)
dsl go 50 (R2995.00) as DSLXtreme uncapped (R2995.00)
dsl go 100 (R5995.00) as DSLXtreme Xtra uncapped (R5995.00)
hence the FUP and respondent mail:
"Lite" average usage of up to 1 GB per day (roughly 30G, + 5G)
"DSLXtreme plain" usage of up to 2 GB per day (roughly 60G, + 10G)
"Xtra" accounts usage of around 3 GB per day (roughly 90G, - 10G)
The difference between these two services are as follows:
With
DSL Go you pay for a "set" amount of GB of data per month and you are "capped" at that level. If you use all your allocated data before month-end you lose access to the Internet for the remainder of the month unless you "top-up" your data. This is therefore NOT an "uncapped" service.
What makes this service different is that as you have paid for the full amount of data allocated any data that is not used by the end of the month is carried over and added to the following months allocation. You have paid for the data so it is yours to use whenever you need it and it never expires.
With
DSLXtreme there was "NO set" amount of data allocated to your specific account. You were not "capped" at a specific level. However a specific amount of data was allocated to a common pool of data dependent on the package (standard, Lite, or Xtra). Depending on the overall usage of the pool of data it was possible to have access to more data than you actually paid for as you would be subsidised by those that used less than the amount allocated to the pool for each user.
On the Lite service it was possible that some users would only have used say 15 or 20 GB in a month while other users might have been able to use say 35, 40 or even possibly 50 GB per month.
Additionally, even if you did reach the variable "threshold" of "fair usage" you would not have been cut off from the internet. You would only have been asked to reduce your usage for the remainder of the month e.g. to only use the service for browsing, e-mail, and light downloading but not to continue with heavy downloading until the next month.
There was no "set" cap or limit and you would have continued to have access to the internet the whole month
unless you refused to be fair in your usage and continued with heavy downloading after being asked to reduce your usage.
You may say that having lighter users subsidise heavier users is not ethical but then all standard ADSL services would be unethical as this is how the system works, except that you are normally "capped" at a specific level.
If you purchase a standard 10 GB ADSL service you generally actually only pay for about 7 to 8 GB of data. If you then reach your "cap" of 10 GB you have actually used more than you paid for and you have been subsidised by someone that has used less than 7 or 8 GB of data.
If you use all 10 GB the ISP generally makes a loss on your specific account. The ISP generally only makes a profit on accounts that use less than for example 7 of the 10 GB and breaks even on an account that uses about 7 or 8 GB. If there are not enough light users to subsidise the heavy users the ISP will not even make a profit.
That is why unused data on a standard "capped" package is not carried over.
That is also why so-called "pre-paid" data is more expensive per GB than a "capped" package and why "pre-paid" or "top-up" data usually does get carried over.
TelkomInternet take this even further and you can generally use up to roughly twice your "cap" as they have a much higher proportion of lighter users that subsidise the lower proportion of heavier users.
Although service was market as uncapped - you are still only allowed the above data usage VS IS's express uncapped rules of threshold where you actually do have an uncapped just at half speed after you have crossed your threshold, BUT you can still continue to download at your hearts content.
You were never "only allowed the above data usage" on the DSLXtreme service and if you reached the "threshold" of "fair usage" you would still have been able to continue to download but just not "at your hearts content".
