Made a purchase with my debit card. Merchant shows that a Discover Card was used (I do not have a Discover Card). The payment cleared my bank account. I returned the item to the merchant for a refund. Shouldn't it go back to my original debit card account?
If you funded the original Paypal payment to the seller from your bank account or a card then once marked refunded/completed it will automatically go back to that bank account or card. Normally it can take a few days up to a week to go back to a bank account and a bit longer for a card, Paypal say allow 30 days for a card (1 billing cycle) but its rarely that long. (Can vary according to country though). https://www.paypal.com/us/smarthelp/article/FAQ1212
