As i said i have 50 neg balance from 2 years and nothing happens. (only have paypal account freeze

Did you have your full name and address on there? I'm guessing you didn't? If they have those details something tells me they won't just accept the losses if they can help it.
Even if paypal have your bank on file and your credit card they will not take the money (the negative balance) from your bank or credit card because they simply can not do this it would be considered as theft
