You can of course get your CC company to do a chargeback but that would just result in your PayPal account being closed just for a mere few dollars?
And of course, I got paid tons to say this all because this is a forum and we all are paid to post here.
If I were you, by now I would have moved on and restored my site the way it was supposed to be (even if I didn't have the latest back-up). You are just losing your traffic and I am pretty sure you realise that.
Try having some common sense and things could be a lot different you know?
