I have an Ubuntu One Mobile subscription, which I can see in my subscriptions page:
I no longer need my Ubuntu One Mobile subscription, so click the link to cancel the Mobile service subscription:
Then confirm that request to cancel:
But the process ends there showing a "Something has gone wrong page", and my subscription remains active :(
The same problem occurred when I attempted the same a few weeks back, so not a temporary problem I'm thinking.
Any input gratefully received.
I would like to report this problem directly to the maintainer of this part of the Ubuntu site but cannot see how to do that.
