Can You Claim a Refund Through PayPal?

Request a Refund
The easiest way to get a refund through PayPal is to ask for one directly from the seller who sold you the goods or services you bought using PayPal. In the seller's account, that person would go to the payment history, select your payment and click the 'Issue a Refund' button.
Open a Dispute
If the seller isn't willing to refund your money, open a dispute with the seller through PayPal. You do this by logging into your account, finding the transaction ID of the purchase in question, going to the 'Resolution Center' tab and clicking 'Open a Dispute.' According to PayPal, acceptable reasons for opening a dispute include not receiving an item or receiving an item that was 'significantly different than it was described.' Be prepared to provide documentation to support your side of the story.
Upgrade a Dispute
If you can't resolve a dispute with the seller using PayPal's dispute process, you can escalate the dispute to a claim. The claim process is based on arbitration, in which PayPal will review the cases presented by both sides and decide in favor of either the buyer or the seller. In some cases, the disputed amount may be split between the buyer and seller.
Considerations
Contact a seller for a refund within their specified refund window. Most merchants give you 30 to 90 days to return or exchange an item. Per section 13 of PayPal's user agreement, you have only 45 days from the date of purchase to open a dispute through PayPal. If you aren't getting results from the seller, make sure you open the dispute before this window ends. If you have to upgrade a dispute to a claim, you must do so within 20 days of opening the dispute.
