Why is my iCloud disabled

Are you talking about your Apple ID?

Start here:--> If your Apple ID is locked or disabled - Apple Support

If you mean something different, please better explain your needs.

I have lost most of my contacts. I still have numbers in my favorites but no names attached to most of them. I think it happened after last update. I havw tried shutting down and restarting and several other online tips but to no avail! Any advice greatly appreciated!
