3. Click the 'Details' link next to the payment you want a refund for.
4. Click the 'Click here to resolve' link.
   
5. I didn't cancel my PayPal recurring payment which is why I accidentally paid for a service I canceled. so I need to check the 'I have a problem with an item I purchased' option, but you might check the other option depending on your situation.
   
6. Click the 'Continue' button.
7. Select the proper option and click the 'Continue' button again.
8. Select the purchase category from the drop-down menu, enter a straight forward message to the seller and press the 'Continue' button.
9. That usually all you will need to do. The seller will receive a message and refund you the money and the dispute will close. If the seller doesn't refund you the money, you can then escalate the despite to a 'Claim'.

If you're trying to cancel a PayPal Subscription or Recurring payment try this.
