ios 7.1.1 icloud enabled and all local saved calendar data got deleted

Hello all,

I'll need support on my issue. Hopefully somebody can help out.

Situation ahead the issue:

I phone 4s

IOS 7.1.1

Calendar was just local in use - no googlemail account or something else.

My actions:

I enabled icloud and all calendar data were deleted.

Situation now:

All data's are still not available. I believe they must be on the phone somewhere local.

I took sure that all calendar accounts are visible. All Accoutns are enabled.

I just checked icloud over the web browser, but I didn't found anything.

I'd like to ask the magic question:

Is it possible to restore the local data's of my phone? Is somebody aware of any ideas?

Is it better to talk direct to the apple support:

Accually I'm so happy about some help.

BR,

Hendrik
