For now, go to the credit card you really paid with (Paypal is just the mediator) and phone the 1-800 customer service number. Ask the clerk about a chargeback.
Cards have deadlines on chargebacks too, so phone now. Have your transaction numbers,dates, payment amounts and proof of shipping hanfy to help her process your refund.
