Locked out of my iPad for security reasons
I am locked out of my iPad for security reasons and don't know why this happened as I was reading the daily paper and it when into lockdown. To activate this it needs my Apple ID, ending with iCloud.com, which is not correct. I have tried various names, initials and words that could relate to me but to no avail. Is my only option to go to an Apple Store for help. Apple online help will do nothing without my receipt for this. The iPad is three years old so don't have this now. Please please can someone help me as I am no wiz kid .
