Ok then try this not quite so hypothetical example:
An elderly couple want internet to watch movies and skype the grand kids in Australia or America etc.
They have no concept of capped, shaped freetime double data etc.
They just want affordable internet that meets their needs at a price point.
A family member from America, whilst here on holiday, sets up an Afrihost Unshaped 100GB account based on the fact that 100GB is more data than they need and unshaped is essential for Streaming and Skype.
Several years later you have added Double Data, they don't care, they probably don't even know.
Then you add Free time, but they are mainly streaming and skyping in the evenings so they don't notice.
They are still happy within the 100GB they pay for.
Now suddenly you take away the package they have been paying for for several years add data that they dont need or want and remove the unshaped aspect which they do need and want.
The family member is in America, the Old couple don't understand your email and, rightly assume, that the account will default to what they have been paying for all along. But instead it defaults to a totally different package.
That my friend is borderline "bait and switch" and I think the Consumer Council will be getting several similar reports.
Cancel Dubble data and free time, that is your prerogative, change someone's package from unshaped to Shaped just because it suits your bottom line is not.
