I bought a item from eBay paid through PayPal money came from the. Girlfriends bank cars. The item was faulty. He Tryed to fix it a week later. I had split up with the girlfriend. Then he refunded my money to PayPal which goes to her bank card. But she had cancelled her card where would that money be. It's not in paypal

Would probably go back to the sellers account. I presume you don't have a paypal account

Would likely be an orphan payment still with bank that girlfriends card originated with, if PayPal account was asked to refund to card.
