As already stated I can't see which payment is frozen and which isn't.
I strongly discourage you from already trying to rollback your PP payment. So far we not had a single 'issue' with the account. When now people start asking for rollback this would prove PP is right about not handing the funds to us, while it's highly unlikely that they would transfer the payment back to you either, since it *could* as well be a valid completed transaction and rollback was the wrong thing to do then. When you want to step back from your contribution to the project, please contact us, not PP! Thanks!
When you decide to contact PP, I recommend to ask them to re-check the classification "pre-sale vs crowdfunding" since it's plain obvious that Neo900 is the latter and not the first, and to tell them that no matter if they understand it or not, at least you seen the warning on neo900.org frontpage and the TOS and you consider Neo900 project a crowdfunding thing and want the money available to us rather than sitting at PP.
