I think I'm a bit confused...so OP still has her 11k right? Her account is still negative with PP?
The way I read it is that her paypal account was -11K when paypal took the funds to pay back the buyer so she transfered the $11K from her Chase account back to paypal to bring the balance to 0. At this point, she was out the money and the bag.
As for the chargeback, Chase put the $11K back into her account, perhaps on a provisional status(?), and will be duking out the dispute with paypal. If Kristie wins the dispute with Chase, then paypal will have to reimburse Chase the $11K.
