Paypal refund
Paypal is a bank (XBank), and banks make money on float (interest on the time they hold your funds). That's why they hold funds transfers for 3-4 (at least) business days. Anyway, call and ask for a supervisor. The CS reps who man the phones are only authorized to read a screen. The supervisor will reverse the transaction and you'll get credit in the normal 3-4 days instead of 30.
