I recently refunded a client of mine - it automatically took a withdraw from bank as my funds weren't in the correct currency which i was pretty annoyed about. The refund amount's to £29,92 [$60] - I checked my bank statement and paypal took out £38 - i have no idea why.. any reason why they processed more?
They can't take withdraw from your bank by wire though. If they refunded the money with your credit card, then it is possible that the extra fees was taken as the credit card usage charges. If you don't like this, and want your money back, you can call your bank account and do a chargeback! and you will get your money back!
