Geoffrey beal is an asshole in my humble opinion... As we've told you before, they won't sue you, and if they did and they won, you have no money, they have nothing to gain either way... You've acknowledged them once and got the expected response...I generally don't advice to ignore it, but in this case i' am going to advice just that..you have nothing, apparently they only have an email address for you, so you can't be "served"....If i were in your shoes, I'd delete the email block the email address from my email progrom, and go on with life..
