I have come across a few Ubuntu One questions during the clean up like "cannot sysc", "folders missing", "logs me out" and such. Some have Windows related questions too. 

What is the correct or proper answer given in these situations. 

I see this as more of a Canonical issue. They have their cloud issues and storage problems. They allow purchasing of applications and responsible for the safe keeping of users files. 

They have their own support page http://www.ubuntu.com/support

and contact information https://one.ubuntu.com/help/contact/
