Q: I have accidently deleted my icloud acount so it doesn't exist anymore, how can I restore it?

According to some links in

http://www.apple.com/support/icloud/

There is an article which also suggests at some point to

contact iCloud support more directly than in discussion...

•iCloud: Account troubleshooting

http://www.apple.com/support/icloud/contact/

The database in the first link may be enough, once you

find the topic, however troubleshooting link may help.

And there may be some shortcut, to contact via an Apple

support or itunes store page, but I don't use this & do not

know exactly where to direct you in that matter.

PS: did the reply to your duplicate thread question help?

Good luck & happy computing!
