Hello ~ Take a look here for more info:

If your Apple ID is locked or disabled - Apple Support

If you forgot your iPhone passcode - Apple Support

We need many more specifics.

What we’re the exact steps you took? Messages you saw (every word)? Current iPhone model? iOS version number? Things that worked? Things that failed?
