Wow! How can you commit to sinking so much time into an account, knowing this could happen to you at any moment. If this happened with my account I seriously doubt id return to the game with a new one.
Jagex need to recognise that this isn't just the end of the road for that account, it will often be the end of the road for that player too. They've done so well to expand their player base since launching on mobile, but it will all be for nothing if they don't start improving their customer support.
