disabled icloud account
I've had my iPhone for about 3 years (2nd hand) and whilst resetting I set it up with a new icloud account as I couldn't use my old one for some reason. Now I have been met with an activation lock, and tried my icloud account that I use normally as the one I used to set up wasn't in my mind as I don't use it. I then realised which account to use but by then my icloud account had been disabled for security reasons. I then go to rest my password, and the email it redirects to AND the security questions are incorrect. I have no idea what to do, I am an honest person and haven't stolen this phone or anything but I am perplexed how to get out of this situation. help on resetting my password??
