I'd help you but you'd probably sue me too.
Fun fact: You can't just sue people for petty reasons like this. You will end up having to pay court costs, costs to the party your suing for their time, and likely be in contempt of court which is punishable by anything from a warning to jail time. Try again asking nicely and maybe someone will help you.
