How did they keep your money? Was it just a small amount that you couldn't be bothered with so you let them have it? (going by how well your products seem to be doing that's unlikely)

Otherwise I can't see any legal way that they (or PayPal for that matter) would be able to keep anything beyond their transaction fees.

Simple: they close the account without appeal and there is no way to contact a human.
