My iPad is being held for ransom I was able to restore my iPhone and iPod but my iPad is "offline" preventing me from getting out of lost mode.  I also have a call in to Apple.

I've changed my Apple ID password and had to cancel my credit cards.

Any help out there?
Take the device into an Apple Store and explain the situation to them. Under certain circumstances they may be able to fix such an issue (for example, they are able to remove an iCloud lock from a MacBook, but it takes several days and several checks are done to ensure you own the device)
